Asteroid

@ apollonianking: I know, it is not really a 5-stars game but it's my firts one, there will be music soon (I hope). Furthermore, it's clearly said in the instructions that you have to shoot the asteroids, but you can shoot the ships too if you have the green missiles... That are power ups !
So your are wrong in this point : there are 3 kinds of power ups (health, shield or powered missiles).
About the graphics and the sound, you are right.
That said, thank you for your comment, I'll try to improve these parameters for the next time.

well, thats some new idea, shooting asteroids instead of your enemys

are you sure they are enemies? because i wanted to destroy the earth, but they're protecting it from my asteroid attacks.. xD

Leveling up doesn't seem to make anything harder except asteroids come at a slightly faster pace which doesn't really make much of a difference. More or stronger enemies would make the game somewhat better. Power ups and always nice to see, having a tutorial that says what we're suppose to do as well as what each power up does would be great.

You are not going to like this: The game is almost terrible. Here's why. The graphics are bad, the sounds are coming from a mouth, there is no music or ingame menu, no matter what you always lose the game, and it is never clear whether to shoot the asteroids or the ships. There are also no power ups. Still this is a good start, don't get all weird. At least you actually made it yourself.
