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)

(it runs faster)

-You can upgrade at any time in game by pressing P or Esc to pause the game.
-Shields are most important and should be purchased first.
-Holding shift will not only slow you down for better control, but it will also extend, and speed up your options that spin around you.
-Trinity Attacks will increase your chain multiplier which gives you more points for upgrades

All the rest of the info is in game

great game

great game, but a bit too hard. maybe it's the fast pace mixed with the controls, but overall i liked it. my only sugestion would be to perhaps slow it down slightly and maybe put in some kind of beginner mode. other than that, i love the concept and everything.

i have seen many games in my life, but this is the first of it's class! an anti-shooter game. BRILLIANT! it isnt one of the many old shooter games that i expected. there are a few things that could be inserted though. add a health bar so it wont be as hard. but the game is still amazing. im very impressed.

Very nice concept

Its a great idea and all, but you die way too easy. I am not taking alot of ponits off of this becasue it could just be because i sux. Mabey a health bar or multiable hits before death could be useful for the...less skillful population.

Cool Idea, too hectic and i suck with arrow keys:D

well made but could be improved


pretty repetitive
