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 intesting

It reminds me of Noir because its serious and has alot of quotes that are very interesting, I love it, thank you for making a very nice game, you should make a sequal.

The controls...

Its a good game but it seems like i go through some of the bullets and the controls are very hard to use.


Rated 4.5 / 5 stars

Not bad but...

It is pretty good but, I have a 360 controller and I don't believe it works. I have tried to get it to work but it does not so unless you have a better description on how to make it work, I do not think it is possible without first knowing how to make this yourself. All in all, the game was pretty good, and keep at it!
