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

interestingly orignal.

this is vary interesting and original, but could use a little working on. its a little to easy of a game and therefor got old ofter a good 15 mins of playing. the fact that i could play with my xbox controller was vary appealing and made it a little funner but it still got old. in the future if you decide to remake or make a sequel i would add some alternative characters or mebby an explodeing bomb/mine thing for enemys to trip over. plus a change in music would be nice. other then that its still a good game.
