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)

Download the stand alone version here /downloads/flash/greymatt
(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

wow... this game... is driving me insane... its incredably frustrating, and addictive, and quite honestly there is nothing i can see that is wrong with this game besides the fact that its insanely addictive... also, the ocasional psyciatric quotes and odd music give it an insanely trippy feel. also, im sorry the only adjictive i can come up with is insane, but thats what this game is it is truely insane and its driving me insane. keep up the good work.
