Great game, and great concept! Definetly 5 stars

Wonderful!

Amazingly fun game!!!! I could play this for hours.

Such a great game with amazing gameplay, great graphics, and a good new concept. I definitely reccomend this.

I've played dozens of tower defense games on the iPhone, this one is by far the best. 3d level design works great, though this game would get 5 stars if it didn't crash as often.

I saw this at the WWDC and I loved it!

Ive been wating for this app for a while and its finaly here! Graphics, ,consept gameplay, fun factor, I rate it all with 5 stars. Best Tower Defence game on the app store hands down! Lots of cool added features with facebook and twitter in a challenge mode too! Great job guys! To people reading this, Download now, this is a game you will not regret getting.

Yay first to review anyways graphics are phenominal and gameplay is very fun and entertaning this realy breaks the technology for mobile phones

This game is awesome and at a fair price! A game I'll keep on coming back to for my on-the-go entertainment needs!

its about time the greatest tower defence game (for the next year at least) was released its been a long worthwhile wait.

Been waiting a few months for this great release! Thanks a ton ngmoco

The pinnacle of iphone gaming.

BitMob.com impressions - Either I’m going blind or this game is insanely dark (crank your phone’s brightness way up before playing). I wrote that first impression 90 minutes ago -- before I became hopelessly addicted to the iPhone’s latest tower defense game and was unable to pull myself away long enough to write some impressions. It’s kind of like a cross between Field Runners (tower defense on the iPhone), Mario Galaxy (you’ll use the entire small planet, rotating it with your finger), and Puzzle Quest (the way you progress from one area to the next). This game is so ridiculously engrossing I can’t even see straight and I won’t put it down. In fact, I’m kind of annoyed that I’m writing this and not playing it right now. Maybe just one more game...

The app launches, gets to the main menu, then I immediately get dropped back to my home screen. Terrible.

I downloaded this game after Apple's keynote, and was pretty excited for what looked like a very high quality tower defense, but the game won't get past the initial screen. I've reinstalled and tried launching it about ten times. Every time it makes a different distance into the load but failed every time. Don't waste your $6 on this, it doesn't work, at least not on the iPod Touch.

It's nice to see developers pushing the TD format to new heights. Building on a sphere is a fun and refreshing break from X Y grid layouts. All your standard TD elements are in place. I think the main problem I have is in the theme. Space is a tired and old genre... Here's hoping that we get Plants vs Zombies on the iPhone someday!

Smoothest and best TD game I have played. The controls and the strategy behind the planets is great and results in some deep strategy involving getting all the accomplishments. *****

I have a few other outstanding TD games, but it will be hard to go back to them after playing this.

I've been waiting for this game for a looong time, and now it's finally here! It's totally awesome, and with what they said about 3.0, it's gonna go through the roof! Get it now, so you don't miss the fun!

This game is funky

I like it, it's got really great in game music too. Try it if you like TD at all. Things I don't understand or want changed: 1)Why a 10 tower limit? It's not that hard, if you NEED to have a limit, make it around 25. 2) Explain our mission, there's no reason to try to win a game with no storyline at all. 3) Could you maybe work on making it just a bit less crashy, the levels are amazing and great to zoom around, but even after I restarted after I downloaded it, it crashed the first time. Not too big of an issue though. 4) 5.99? are you kidding me? The Sims3 I understand, but come'on ngmoco, we're in an economic recession, do we really need a game that costs $6 bucks right now? Of course not. I personally feel it was money well spent compared to the quality I've been getting, but could you drop it down slightly? That's it, I'm done. I'm going to go play StarDefense™ now, for it's engaging gameplay. All those interested, please buy it now, and support ngmoco as they continue to pour out quailty applications to be devoured by the general public.

Wow. This app is just.... wow. I have barely played it, but I don't need to see any more. This game was hyped forever, and I can safely say that it is beyond fantastic. Keep it up, ngmoco:)!

I've played MANY tower defense games on the iPhone (funnest among them - up until now - being Geodefense and Field Runners). What ngMoco does with this app is literally (well, actually: digitally) create a whole new world of tower defense AWESOMENESS. The graphics are simply incredible. I've seen NOTHING like them on any other iPhone game. The soundtrack is aurally delicious; just wait till you pipe this game's sounds through headphones- WOW! And, above all, the gameplay is executed marvelously. I'm seeing hour and hours (and hours) of StarDefense delight in my immediate and far future! I showed this game to my buddy (who, by the way, does not generally care for tower defense games), and he was BLOWN AWAY! I almost had to fight him to get my iPhone back. Anyway, this is day #1 with the app, and in case you can't tell, I am VERY pleased. The honeymoon's going to last a LONG TIME with this sweet app. I can't wait till our (mine and this sexy app's) 50th Wedding Anniversary Celebration! Thank you, ngMoco, for once again setting the standard on not just iPhone games, but on iPhone games DONE SO RIGHT!

I love fieldrunner but this is amazing!!

Star Defense marks my 475th game -purchased- for my ipod touch.

Its a very different kind of td with its highs and lows but please update with more features because even though this td is great it needs alot of improvement. - allow the towers to be close to eachother - high scores on iphone itself not twitter - all stages should be playable in challenge mode - balance campaign and challenge mode so that its a little bit easier i cant imagine young kids passing the 2nd planet in this game. - a fast forward button - maybe 75 credits to start with on the harder modes

Sentinel is better for tower defense.

Seriously, ngmoco should be proud of themselves. They made a terrific game.

Perfection as far as TD games come. Do yourself a favor and download this, superb quality and gaming.

Been waiting for this game since i dont know when LOL, actually im glad you guys finally launched it. Can't wait for 3.0 and now this has made this week even better!!!

I've been waiting for months to get this

Great execution of a whole new dimension to tower defense. Well worth 5.99, and that price will drop in time. Great fun game, definitely a must-have for TD fans! And I'm looking forward to the OS 3.0 features demoed at the WWDC keynote today..."Bam -- a whole new galaxy in my pocket!"

I have never player any type of tower defense game before, so I was unsure of how easily I would catch on. Well, I had nothing to worry about. Though a reference screen for the types of towers would have been quite helpful, I caught on within a few minutes of opening the app. The graphics are beautiful for the seven planets, and there is a “Commendations” screen to log your various accomplishments. Though I have by no means tired of the game yet, I hope that the developers will add more maps, towers, and creatures beyond those provided in the seven existing planets. In the settings page, there doesn’t appear to be a way to store different save files for different users, like there is in some other popular games, but the ability to disable both effect sounds and background music is useful at times. Overall, I’d say this is an thoughtfully designed and well made game. Well worth my $6.

Very good graphics, sound and gameplay.

As a lover of "The Creeps" and "Field Runner" I love this game. The 3d globe makes it feel and look fresh. I love the challenge mode!

LOVE all the little audio details (try panning out). the 3.0 OS rollout will ensure this remains fresh for months to come but excellent as-is

...literally, because I just can't believe I'm playing this on a cellphone. Best tower defense game I've ever seen, on any platform.

Any previews of Star Defense were kind of exciting, I'll admit. Once I bought and played it, I had underestimated the detail of the planetoids on which you wage war. The textures and creep models are pretty impressive and some of the level design has a very Super Mario Galaxy creativity to it. Everything runs smoothly, a nice spacey scene revolves around your planet (even though its the planet that revolves in space, but its all relative), and the presentation and interface is all very neatly packaged and professional. However, the nuance of three dimensions did not last.

This game doesn't hold a candle to Geo Defense. I appreciate what these developers were trying to accomplish with 3 dimensional space, but the gameplay is thoroughly unstimulating. Sorry devs! At $0.99, this game would be worth it: At 6 bucks, it's not. Five stars for innovating the industry, minus four stars for overcharging me. Net review is hence one star. By the way, don't even think of charging me 6 more bucks to get more levels when OS 3.0 comes out!. I recomend... Field Runners Peggle Geo Defense

Graphics, controls, and online content are good, I'll give it that. But the game just kind of gets boring. Maybe I'm just not giving it enough of a chance... There are too many other great games to waste my time with.

Well done, fun game. As with all good games I find it's the post release support (fixes, enhancemet requests, etc) that tend to make the good games great games. Here are a suggestions: - Auto Save - Add option to toggle dropship sound on/off. - Consider adding tower awareness to units that fully resist. No need attacking units they can't damage while others units pass though unharmed. - increase gameplay by revisiting tower effectiveness vs cost vs game duration and resist effectiveness Some of the towers (and upgrades) don't get used due to the their lack of effectiveness. Resist units force us to be balanced in our defenses but games end before we can utilize the costly towers - mainly because of full resist units. Electric towers need to be cheaper or more effective, possibly a faster rate of attack. Slow towers need to be much cheaper, possibly $45 or $50. Look at all of the towers effectiveness vs cost vs game durations and improve as needed. - Scion bird wave way to fast and too many. Slow towers aren't option due to cost/effectiness. - Consider reducing the immunity of the unit resist to extend gameplay. - Be kind to the user communities wallets :) especially since work needs to be done. - Really like to see aggresive changes before more content. If you're looking for a good strategy based tower defense game with great potetial and this is in your budget I'd recommend buying this game. SaltiDawg

Best tower defense game ever, on any platform. has a great variety of enemies and different towers to combat the enemies weaknesses and strengths. The achievements are obtainable and practical. one of few ipod games that keeps me coming back.

I didn't buy this game so I could look at your ads!

The app is decent enough, but as the showcase for what the iPhone can do, they need some serious work on their controls. You'll spend 20 minutes getting up to a good level only to find that when you try to tap a tower to upgrade it simply won't take it, or it will rotate the world, or it will pick the closest tower to it. My favorite is when you tap on the countdown to start the next wave and accepts the tap but, as a bonus, it spins the world to the left quickly so that you lose track of all of the aliens.

This is one of the few "must-own" games for the iPhone. If you like tower defense in the least you'll love what Star Defense has to offer. At $0.99 there is no reason whatsoever not to buy it. It showcase amazing graphics and visual effects (for the iPhone) and manages to still perform solidly with few hiccups, crashing or framerate problems. The tower defense gameplay is simple but challenging, with 5 types of towers and enemies that are resistant to certain types, making you employ different tactics for each level. With the built-in +plus system you can set up a gaming profile (similar to XBOX Live) and share acheivements, scores, and challenges with your friends who also have the game. What are you waiting for, click buy.

Fun for about 2 hours. Very few levels, very few towers, upgrades are bland. This game plays like a demo. Needs more levels/towers/upgrades/enemy units before it will be worth your while.

The tower defense space is crowded with a variety of different themed games that stretch from being excellent to terrible. Star Defense has received enough hype over the past few months that you almost assumed it would never live up to. Undoubtedly, the game will generate a flood of money to the publisher and the devs behind Star Defense. The question remains “Is Star Defense worthy of your money and more importantly your time?”

This game is way overrated. There are much better and more interesting Tower Defense games out there that are cheaper and have more replay value.
