Impossibly hard.
Change the movement to WASD, make the levels easier, add different weapons etc, and try improve on the layout a bit, then it might be a bit more fun to play, 1/5 at the moment.
@Seeker - go to pause and then surrender, you have the choice of restarting or going to the main menu.
Nice game, like the idea of the generators, some stuff could be better though, but never the less it's fun, 4/5
