A simple fun re-imagining of the arcade classic with gravity added.
Over 1000 asteroids on the later levels… Each with collision detection and its own gravity.

Have fun!
I found it much enjoyable then any other version of asteroids I’ve played. If you make it able to work on Java 5 then Ill play it at uni too 
But I found it did get a little repetitive still, if you going for something a little different I suggest adding more too it.
For example adding a shield power up, different types of weapons. Maybe on some stages you need to protect something other then yourself like a planet or another ship. Could also add another type of asteroid like a iron core one, or have some other dangerous objects like a black hole 
Very nice! Extremely polished, I love the text transition effects (where the lines extend and vanish, kinda).
The physics feel solid and act mostly the way you’d expect them to (although sometimes the wrap-around kinda confused me (I bet that was a pain to code, btw)). Once or twice, I got stuck in the middle of a large cluster of asteroids, seemingly getting sucked in as soon as I hit it, but shooting my way out was easy enough.
It does get a bit repetitive, yes, and with 9 lives, you can go on playing for a long time.
I only got two power-ups, rapid fire and spread shot (plus health once or thrice), and found them enjoyable. Rapid fire has a tendency to speed asteroids up to insane speeds, though.
If I may suggest features: (please ignore if the game is already complete)
Split the game up into three or four “worlds” of 8 levels each. Each world has a unique color, and perhaps different configurations of asteroids (plus world 2 is harder than world 1 and so on).
Have a mini boss on level 4, and a final boss on level 8, each unique for each world.
Add a scoring system, with combo bonuses and score power-ups.
Very much fun ;D
Hey, you forgot to add the UFO!!!
It is a pretty game with a bit elaborated physic, good work.
Good stuff. Maybe the difficulty curve could be a bit steeper; although I liked the game from the start, it only really started getting exciting once I finally lost a life around level 20… Also, I guess I must’ve hit something by mistake, but the game started from the beginning with sfx and music disabled before I finished my go. 
Asteroids as it should be! Great stuff!
Got to level 41 on my first try
Really impressive!
It looks great and it’s fun to play.
If I had to pick flaws (and, well, it’s no fun if I don’t) then they’d be the following:
Keep up the good work!

I loveed playing the original one, and this one is really well done so I love it too.
one notice, I found the ship reaction a little too slow ?
Hi - Thanks for all the feedback! Its always nice to here when people appreciate your work.
I still considering about doing java 5 support, it should need many changes but doing all the QA again for java 5 will be some effort. Its a pitty that java 6 has been out so long but still not supported widly enough.
The critizm is fair. The are a lot of lives and it takes a long time before the game gets challenging. You kind of have to get past level 20 before things start to get interesting.
The game is complete but I’m looking to port to other platforms at some point and I want to do a sequal so hopefully I can take some of this feedback and used it in the future. I also want to do a couple other different games using the same graphics style.
There is an issue on slower machines with Key Lag. I think thats why the ship reaction may be a little slow for some. If anybody has any good sugestions on the best way to deal with this, please let me know. Maybe I should ask in the appropriate sub forum.
Sound gets automatically turned off if sounds processing is going to slowly. I might look into this a bit more and see if I can get sound to work on more machines.
Very polished game, I like the graphics style very much!
I agree with the others that it felt a little bit long stretched, as Markus also pointed out it might be very cool to have a little bit more variation? For example different asteroid types, other enemies, colors etc. I dont know if you’re familiar with Piranha? That was an asteroids game you could play with two players on one screen/keyboard, besides it being great fun to play coop with a friend, it had shops in between levels where you could upgrade your weapons with money you could collect from shooting asteroids (http://www.mobygames.com/game/dos/piranha/screenshots/gameShotId,3865/)… Those features gave the game excelent replay value!
PS: Did you write your own softsynth for the music?
Very nice game. Well done, lukecrashtestgames.
Love it.
One thing I kept hoping would happen when large clusters formed… I wanted to see the asteroids in the center compress together into tougher asteroids with more gravity.
I did write my own soft synth for the game. Actuall, the biggest part of the development time was taken up doing the sound and the sound engine. I decided to take my time to learn about sound in detail. I became really obsessed researching and experimenting with gutair strings, distortion, flangers, wah wah and trying to invent new ways of doing reverb. I wasted a lot of time but its good, I have a much better appreciation for sound in games now.
I was thinking a bit about grabbing one of the compressed sound players available for java but I was a bit nevous about them. Anyway, now I am happy to have a 45k downloadable java game with very fast loading times.
Cool, there should be more games with audio synthesis IMHO.
Brilliant looking and fun game. Well done! Just one thing. On my computer (Dell Inspiron 9400) I can’t hold down Up Arrow + Left Arrow + Space at the same time (some sort of hardware limitation). I believe the limitation exists on many keyboards, so having the fire key as Ctrl or something other then space would be better.
