This is such a cute game! I did have some trouble in the first level understanding how to not drain all my energy, and probably played it more times that I should have haha.
It would be nice if the first couple levels didn't have such a slim margin for error and allowed the player to "soft fail" before moving on to more difficult levels.
I did really enjoy playing and it felt incredibly polished. If you continue to work on it after the jam, I think you have a really solid idea for a mobile game.
