Nice game. Great art (and sound) would have been more impactful with animation for your character, even if you did single frames for each action - one for idle, one for move, one for jump. I'm surprised you've used python, been a while since I've come across a game done in python. As the other commentator said, you should consider something like Godot for a 2D platformer.

Great work! Nice art and level design but the game have several glitches with collision and sometimes the FPS falls drastically but it's impressive that the game is entirelly made in Python. You might consider make the same game in a game engine like Godot that use a code language very similar as Python, certainly you will like it and will make your game developing process more easy and fast.
