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

At first, I didn't like it at all. The only reason I kept playing was that I liked the little anecdotes about reality and the human mind in between levels. But I started to get the hang with it and had a lot of fun. Also a very cool variety of enemies. Well done.

Awesome Idea, Awesome Game

Love the game, my only problem with it is when there are a lot of particle on screen it gets a little laggy, which is expected. I couldn't tell if you used bitmaps or not for this because it was so fast, but if you didn't, I highly suggest using bitmap data

would be nice if you tweaked the keyboard controls

My only gripe is that the controls are not flexible. I hate that I have to lift my hand off of the arrows to pause because that leaves me open to attack. so this minor detail kind of limits your ability to strategize and the only way to upgrade is if you are really quick, can manipulate their shooting patterns, or just kill everyone and use that mini break between waves. this obviously gets a little difficult to coordinate in the later levels in which you get almost no breathing room.

well then

that was a new experience, i liked the part where it said "take your meds" lol but anyway, it was very hard, those ones with the tails should turn slower or stop to turn, cos they wiped my out of lives completely, even if i was going slow with an option(<-- what does this mean? confused me :P) anyways, good going and keepy up :D

It's not aimless running around ya know

This game is pretty amazing , quite innovative IMO since I had only play shooting games and not anti-shooting !

For the snake-like monster , just use shift , slow yourself , get close so your option ( if you don't have any , use yourself) to kill it .

The game pretty hard though..aw wat the heck . 9 stars
