Hey, right the game is a bit too hard. It was unfortunate that I didn't have enough time to create more levels to smooth out the difficulty curve. That way more people might enjoy the mechanic and get a feel for the physics as they are. Out of curiosity, which level did you get stuck at?
I have actually explained the theme in the game's short description - the theme is "platformer with no jumping ability".
I agree that sound and music would be really nice. In general, at least for me 48 hours was not enough to get the production value high enough.
Thanks for taking the time to play it and comment!
