This is a really unique and fun project! For some reason, I occasionally ran into situations where I couldn't jump, but falling to al lower platform solved the issue. I enjoyed the simple left and right mouse movement to control the character. That last purple level is definitely a challenge. Congrats on your submission!

Was fun to play!
Controlling a character by mouse seems odd but with some refining could be a game like "Getting over it" or "A Difficult Game About Climbing"

I think wall jumping is bugged, you can climb vertical walls just by swiping the mouse left and right and spamming jump.
