I actually really like this idea but I think it's a little basic right now, but could be taken even further by adding branching paths, where some routes are harder but take less jumps and others are easier but require more, or by maybe having each area have a unique element to them that have to be avoided in different ways, things like that.
I also noticed that your character gets caught on the tilemap a lot which is pretty annoying, since the only way to move again is to jump and lose coins. You can fix that by adding a composite collider to your tilemap!
