Cool ass game!
Damn, the twisting of the view is the biggest pull in this game! The visuals can either be bleeeeeh (red/black view, basic enemies with little it the way of variation) or cool (red/black simplify the visuals with a "high tech" look, no time to note variety among enemies anyway because your too busy shooting/dodging during a "shifting" battle).
The music is nice and, despite the relatively short game/quick ending, the endgame features are a GREAT touch! Nice flash!
