I did understand that it wasn't meant to be an actual level, but I still feel the level design is the biggest weakness with this game in its current state as a mechanics demo. It doesn't do a good job of demonstrating the mechanics unless you already know them. I think another way of putting it is that the current level is a sandbox, but the next iteration should be a showcase. Still not a real level in that the goal isn't really gameplay, but rather to show off all the platformer mechanics in such a way that the player won't miss them.
