Really love the art style, playing works quite nice as well. Jumping feels perhaps a bit too 'fast'. Menus don't really same to work nicely.
Thing that stopped me playing right now is that I got stuck in the floor. When falling down the corridor with alternating left/right dropping platforms I got stuck under a pile of them, was pushed into the floor a bit and could not get out anymore. Then clicked 'Save', then tried to 'Quit' but that did not work.
Not feeling like doing a refresh again, not so patient today :-)
