Really cool idea, but the hardest thing to play on a laptop. It'd be nice if you could shoot and dash with something like 'z' or 'x'. I imagine this is simple with a mouse, but I died three times with killing a single guy. Or if you automatically aim in the direction you move in.
The bright white everywhere was kinda tough on the eyes. I can't tell if that was meant as a distraction to make the game harder. If so, mission accomplished.
All in all, solid idea. I haven't played a game that's switched it up like this.
