The screen seems to be too big when in fullscreen, but it's still a good game. I suggest to add sounds and a background music.

Too many levels

I never thought the game would win. However, you need way more weapons and upgrades. I got tired of shoot the same one the whole time. And Magic Missile was way too weak after the 17th level. Seriously?

I'm just messing. Lol. Decent gameplay.

Lack of sound yet pretty good.

there isnt any sound in this flash.
But the actual game play is actually quite good.Liked the idea of using the arrow keys to do a thumb buster game.Quite good.

Nice

good fun. simple time-waster that is definitely worth playing

Not bad.

Things to improve:
Sound: Add some music to make it more fun, more Action Like.
Idea: improve the idea, make it faster.
Animation: Add some more background animation, for example words to pop out like "SHAPAW, OWNED!"
In general, Not bad.
