Just got done trying it out...
Firstly, I really, really liked the scribble-art, good stuff
Kudos on that.
Now for the constructive criticism...
For a game that is supposed to make you feel like your on crack the game actually moves quite slow. I think a lot of this is due to the fact that 1) it takes too many hits to kill an enemy and 2) the ship's movement is somewhat "floaty" which makes it very difficult to control.
Oddly, the music would have fit if it wasn't for the fact that the game itself was not moving as fast as the music was.
I also felt that the ship should be scaled down a bit, when there are a million little bullets coming at you it is quite difficult to maneuver through them in the ship's current size.
The amount of bullets that are shoot in the very beginning could use some tweaking as well, as things get pretty damn hectic right at the start and it seems like it takes an eternity to kill anything. Maybe make the ship's bullets do more damage or allow the laser to do more damage so as to dispatch the enemies in a quicker manner?
Anyways, I really like the feel of this game and I think it has a lot of potential. I hope my comments help. Keep up the good work man
