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)

-Trinity Attacks will increase your chain multiplier which gives you more points for upgrades

Epicly Funtastic

Kinda tricky to get the hang of at first, but once you know what's going on, it makes an amazing game. Very fun and pretty unique game style.
