Awesome project! It's a simple yet catchy idea with fun mechanics, and I love the fact that there isn't just one set path to follow to get to the end; you can choose different paths and still make it to the end. A couple tiny recommendations I would make is A) just a little end portal or something to indicate that it's safe to jump there, super small detail but still something that I think would be a nice touch. B) Definitely ambitious for the jam's timeframe, but if you continue this project it would be really cool to see some random map generation. Great work!
