Awesome short, and the artwork in the game is great, especially with the card art. I think the gimmick of getting cards for abilities is neat, tho personally I'd rather jump be a basic ability you always have, and then have the cards do pretty much everything else, as getting stuck in situations where you need to either burn cards or just stay stuck in a pit from running out of jump cards was unfortunately really frequent. It's still a damn solid base for a game, and with more balancing and designing around the limitations here it'd be a really good time.
