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

having trouble

im having trouble with the flash joystick website any help please

Was good

Was good for about 20 seconds. Once you realize how horrible the keyboard controls are its game over.

Super Fun!

This game is very fun and original! It's a nice twist to just shooting people. All the enemies were very original and different and I like the medicine you can take. This game is quite hard though, which is good and bad. Good in the sense that you don't just get bored but annoying that you can never pass a part you're stuck on. I think the snake (with the glowing tail) is should have a bigger head because you miss a lot when trying to hit it... Sometimes, this game is just fun trying to dodge the hundred bullets targeted at you ;-) Thanks for making this incredibly addictive and original game!

in normal mode, the "take back to main screen" button is directly below the move forward button, so i accidentally clicked on it when i was trying to go to the next level....

this is poor game design since it should not be there, or there should be a warning box like "careful, leaving now will exit your game" etc etc,

Everything else was okay, besides what people have said about the controls
