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

I'm not going to say it's a bad game, but it has its fair shair of flaws! It's more graphic intensive than it needs to be, the controls feel spazy, the Trinity Attack is highly flawed, and the enemies weel, well, both *meh* and cheap at the same time.

It does have it's good points! The psycho-analysis lines were cool, and the concept was great! It's not a bad game, but feels strictly avarage to me.

A fun game to say the least.

Upgrades would be a better solution. Accuracy kinda sucks with the movement. Loved the enemy appearances but the balls they shoot out are bothersome. I did beat it though. Great music its from my fav artist.
