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

Not your average game...

This thing is awesome mostly because you're the bullet and you dont have to shoot :D, but it would be cool if you did... Otherwise this thing is flat out awesome. the control thing with shift wer you slow things down is a good idea because I don't want a bunch of those enemys were you get them from behind you shoot thier large projectiles(the next enemys that have the brain on the back) destroy me ten times. So the shift thing slowing down helps, helps way much to get laser enemys and enemys with thier brain behind them. Still this game is cool and all with the things that I mensiond, but it's just missing that little sprite of awesomeness that it just doesn't have. I give it a 9/10 keep up the good work Edmund, your games are far the best on this site :D .
