Incredibly neat and compelling concept. Despite its simplicity, there's decision-making to be made in deciding how to affect and balance which aspects of your 'character' (the pawn) will change in reaction to a success/fail.
I'd like to see a hack or an update on this where weird abilities can be added. Peeking under a card, swapping adjacent cards, flipping colors, or even the idea of a joker chasing you around the grid. The seamless system makes it very easy to imagine more possibilities!
