Please don't put unfinished practice on Newgrounds. In my opinion, much more polish would be required before this game could be released. The idea of having a game based around a weird jump is cool. However, the game should feel like it is at the very least in a semi-finished state before you release it on a website where people go to play games.
The mouse doesn't snap.
The camera can be flipped upside down.
By holding jump and looking at the wall in the second level you can clip through walls.
The camera briefly clips into objects once in a while (Not a big deal.)
The first level is clearly unfinished.
The second level looks completely different from the first.
