Nice twist on the mechanic, it kinda relates with action-platformers that you have to get back to a point to regain stamina and move further. The graphics very simple and straight to the point. Also, it's nice to see how the mechanics you created shaped the level design.
It was nice to see how you faced the challenge to do this game, reading the description on it.
Maybe these points below could serve as improvements in your future jams:
- I think the audio could be a little more balanced and more harmonical with the effects
- You can make more simple and straight levels in the beginning that just teaches how to play the game. This helps the player to understand how they "win" or "lose".
