Not bad! I always dig the procedurally generated levels, but I'm not here to talk about that.
Because all the time I played your game I got this thought: WHAT IF THE POWERUPS STACKED?
Seriously- some of the games this wouldn't fit at all, but this one? Oh boy! If I could have multiple doppelgangers, or bigger soul multipliers- that would make me take risks! And that's always cool!
