This is super cool! Definitely more complicated than anything I was ever able to pull off back when I used Scratch, and the obby was actually challenging for me lol. If you were looking for tips, I would say try and make the interface a bit more organized? As it is, things are overlapping over each other, and there's not much symmetry. A little more time spent making things look ironed out can go a long way. Most importantly- keep at it! Learning how to think in code when you're young can give you a good foundation for learning more complicated stuff in the future, and it's a fun hobby that can help you meet lots of cool people!
