The graphics seem nice and the basic game play is all right, but it needs improvements to be enjoyable. Especially the wall jumping is a pain to get right, and because you have to walk quite far to the right to advance the screen it's feeling like running into the unknown. Also IIRC the push and pull buttons are mixed up (or the tutorial message is mixed up). It would have been nice to at least get a basic description on the game's page. Sound is definitely missing.
