I just completed all levels, nearly twice actually but the last level is very hard. The game has potential at becoming a fully fledged out physics based puzzle game.
The camera is definitely improved, but could still use a bit more polishment(only when you're near a wall though.).
I had some issues determine where I would land on the platforms. Something that would have made jumping platforms easier, is a black circle underneath the character (the sort of simplistic shadow that would be underneath a character in old games) :-)
I actually found a way to avoid the shuriken launcher, if you go all the way to the left, and then run. I didn't get hit by it. However, don't worry, I did finish the level legitimately on my 2nd playthrough :-)
The levels are definitely hard, especially the last one, I was struggling with that one because I had to jump on the crate and had to get it out far enough. But it was hard because the crate's physics would sometimes go crazy if I touched it or landed on it when it was in a slow bubble.
BUT I found the game very cool, and fun when the crate physics behaved the way I wanted :-D I hope you will develop it further and improve it to make it more complete and polish the features :-) It definitely has potential, and I hope you stick with it, you have a really good game here.
