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

Very nice game, another job well done. I only took off one star because it's a bit chaotic at times and kind of difficult to really play. In addition to the one hit kills the baddies dish out it can be fairly frustrating.

Love your work guys, keep it up!
