This game has serious potential, your game engine seems to have a lot of functionality built-in that most pygame games do not. However, the gameplay itself could be more interesting and satisfying.
I found the energy system unnecessarily strict. After a couple levels I started feeling as though the movement speed was reduced to make the game seem longer than it actually is.
This game pays a fair bit of attention to detail, and I hope to see a version of it that was made in a longer time span than the duration of this game jam :)

Thank you very much for your feedback.
I, the developer of this game hate the stamina system too. I won't deny some parts were a bit rushed, I'm planning to continue developing the game after the jam ends using an upgraded version of the engine. I will try to work on fixing the gameplay loop so it feels more natural and satisfying.
