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)

-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

I was amazed. First I tried this game with a keyboard, and found it nearly impossible. Then, I took your advice to plug in my XBox 360 controller into my computer and try playing it. WOW! It then became a fun and addictive experience. I like to see flash that is creative like this, and the peripheral definitely adds to the game. Nice work.
