Beat it! Very nice, the concept is easy to understand and it matches the jam topic perfectly :) Some additional thoughts:
- Game visuals are very pleasant! I love the glow behind the player, coin explosion effect and of course random hats! :D
- The main thing I would consider improving is player movement: maybe it could be a litter smoother (acceleration based, not going full speed in a moment you press a key), also when being in air releasing a directional key doesn't make any difference, but pressing an opposite one does - but only if you start jump when moving, if you start jump standing still, there is no mid-air control. This feels a little inconsistent to me to be honest.
- Another nice touch would be additional effects (particle/sound) for putting dead body on a platform and unblocking a coin (feedback to player, reward for doing something correctly)
- I love the concept from the last level, that was actually really clever!
Overall definitely a fun experience, great job! :)
