Grey matter is an anti shooter, or a shooter without bullets.
Essentially your the bullet.

Run into the exposed brains of incoming attackers to destroy them.
Killing 3 of the same type of enemy will cause a "Trinity attack" killing everything inside it.

Avoid enemy dangers (flashing bullets, tails, teeth and lazers)

I liked your style and I liked your game. I wish you would have added a storyline though, storylines always seem to get me into the game, and gives me a purpose for doing what I am doing. The other thing that I liked about your game is your upgrade system, I always write in my reviews that I like upgrade systems because it adds to your choice of how the gameplay is. Well done and I cant wait for a sequel!! (hopefully with a storyline!!!) :) good work!
