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

Awesome game, highly original, fun, and I loved the psychology themed quotes. Only suggestion I could make would be to add cheat codes, for those of us that just want to see the boss but have shit twitch reflexes.

good, but hard as hell...

you shud definitly make some different powerups to upgrade in here. also u could make it a little easier... just a little for us losers who suck at this game.. but great job overall. very addicting.

A piece of cheese

I thought this game was good for a few different reasons:
1)The characters were original.
2)The gameplay was clean and smooth and had a different way of killing the bad guys.
3)The level of difficulty was perfect. Neither hard or easy.
4)The atmoshere of the game.
5)Also the music was interesting and matched the way the game felt.

Great game, cool art, good music, but what really sealed the deal for me is when I plugged in my 360 controller. Very sweet. You should make this multiplayer, so you can plug in multiple controllers and do a co-op type deal. or who can kill the most dudes.

great idea

really fun but there are two problems:

1. laggy, even on low quality, i died twice because of lag.
2. need to give warnings on what enemies do to kill you, i keep rushing in to find out wat new enemies do and die because i hit the wrong spot, even though i dont know where that spot is.

other than that good game.
