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

i usually give enemy spoilers on these kinds of games but this is so awsome i'm gonna let u guys figure it out! i agree: shields are far by the best! althought that enemy you saw on the game icon:
you need to use speed up(space) to reach him 'cause he teleports:O nice with all those modes and an upgrade store in the pause menu!:) nice anti-shooter! the player is a black fuzzball? doesn't that stand for energy? one enemy looks like a sperm, another a bull, and yet one a squid. great game in all so i give a big fat 10.good job. -sabrehawk
