I really enjoy the idea of the player nudging fate in different directions – that's a really cool concept for how a player could interact with a game. I think perhaps the difficulty curve needs to ramp up a little earlier and a little more smoothly. That aside, this is the kind of mechanic you could really spin out into a full game.
Oh, and the art is fantastic! Characterful, lively, well animated. It really added a lot to the experience – some really nice enemy designs!
