Very cool and polished game! The card mechanic tied to health is brilliant. I only managed 3:05 at my best run after a couple of 1-minute long runs...
It was interesting thinking about rearranging my cards around. I realized that card slots matter when I got "Player now gets red hair" customization, haha. This main mechanic was great. I wish to see this game (and the character) to be developed further.
One thing I would like to see is that I can move the old cards around when new cards come in. I understand that it is probably a strategic choice I have to make on my positons; however, I think that would make the player have more control over themselves in general. (This part is purely personal opinion)
Great job!
