simple and boreing

not much to it.

Your play button is broken.

FIX IT.

Awesome

Finally. a game with math equations. so the morons might learn some when they play

you could have made more of this

i really liked the idea of this but:
if you dont read every detail of the instructions you dont have any clue what the hell is going on... well ok thats not really a mistake but i find it inconveniant in this kind of game.
also you should really work on the game mechanics. the enemies are often half the size of the screen everything move really fast but the projectiles of the enemies sometimes dissappear in midair. also powerups are collected even if you are not touching them. i think you should work on the overall usability.
Other than that i like your enemy and boss design

what have we learned?

Maybe it was my computer, but the sound was non-existent for me. The graphics were very very sub-par. Unfortunately, I am a giant math nerd and I was really looking forward to actually solving math problems. I was met with a predictable shooter so poorly animated that even my favorite part (the math problems) were illegible. I gave you a rating of 1 because I know some kind of work went into this. I have all faith in you and anyone that submits to Newgrounds that you will hopefully grow as an animator and/or programmer. Cheers.
