Fantastically executed game. Very impressive you managed to kick this out in 48 hours - the art, sound, juicy details, variety, and balance all feel spot-on!
Only con I would posit is that it's not much of a stretch in terms of flavor and mechanics - for a "role reversal" game I was expecting something along the lines of "you are the deck" or even you play as Satan trying to destroy the hero... a little more risk in the experiment.
That being said, the little twist of swapping characters is fun and everything you put into the game is super solid.
Great job!
