The idea of having the ninja change when it can and cannot jump is a really cool one! I'll make sure to keep it in mind! With the "Bouncing off" well, I know it's a problem with the tilemap being many collision shapes but I don't know how to fix it in Godot game engine. Also, I forgot to mention it in the tutorial, but you can press "R" to restart a level and it makes things so much easier.
