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

Seriously, You deserve it

Well at first glance the game didnt looked any special, a normal antishooter, I must say that the phrase at the start caught my eye tough.

While playing I really liked the game, still was just a normal antishooter, the upgrades were good, the music wasnt irritating, the difficulty is actually on a great level. What did annoy me was that u had to look all over the presentation when u went to back to main screen. I entered the boss and actually liked the how you have to kill it.

All of this had made this a very good game, but when I totally felled for this game is when I saw the cast. I didnt imagined that the enemies were so symbolic, maybe its not that special, but I DID loved the cast.

Good work.
