This is great!! The mechanics of leaning to move is super clever and is very well implemented!! It's very much giving getting over it vibes!! Great job!!
I do have a little bit of feedback and I also think I encountered a bug:
I found the font that you used for the text a little hard to actually read, this doesn't take away much from the game though I just wanted to point it out.
And while clearing the very first rock I found myself struggling because I couldn't seem to actually jump high enough to clear it? Eventually I passed it because I fell but my body fell right of the rock and the unicycle to the left and I ended up respawning where my body was so I had passed it and suddenly I jumped a lot higher? I don't know if I was supposed to be able to jump higher from the start or if after falling I somehow got stuck with a higher jump than I was supposed to have but I will say that the higher jump was definetly better! :P I don't think I would've been able to clear as much as I did if my jump was stuck being as low as it was at the start.
I didn't finish the whole thing because that would clearly be a lot of work but this is still a great fun game! You guys did a great job!
