The title screen is so pretty and nothing like the game itself that I have to wonder why you've put so much time into it instead of the game.
I really couldn't control the character. At the end of the day I glued myself to one of the inner walls and waited and that did the trick for the first level. I really think that changing the controls to be more intuitive will change the entire thing, so there is not much to say about level design as it just did not fit the controls.
But again, on the plus side, the title screen is so goddamn beautiful.
