Nice job with the music & Sound FX!
It's an interesting game and pretty fun, but I think I'd prefer the custom level design to be an option, not a requirement. Especially since the game is over pretty quickly. I probably spent more time drawing then I did jumping! 😅
Attaching a screenshot of a weird bug I encountered... When I jumped up to the top of the screen, close to the ceiling, the game completely glitched and turned into this other screen. I had to reload the browser window. (the game was ok after that)
