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

-Edmund & Tommy

a little of this, a little of that...

I was able to play this with the keyboard.

I would have liked to of seen a mouse version. I would have liked to seen a version designed with the keyboard in mind. I lacked these things with no great loss of enjoyment.

I would maintain a sentiment that the "option" feature should have had a greater reach than the teeth of the enemy. It would form a very fair counter attack.

9/10 good game.

Sold out by xbox

I have an idea, why program this PC game for a 360 controller when every PC out there has a mouse? Why not program it for that?

Can you list the quotes you had on there like the ones for stress, anxiety and so on? I liked them. Or did you find them on Wikipedia?
