Thanks for the review!
The camera does seem to be quite a problem (*o*)! I got the camera working on my local version, and will update the game after the voting. In the last level, do you think removing some enemies, adding a boss, and/or enlarging the platform might help? Perhaps the scoring system could be time based, or how many times you got hit or fell (at the end of each level: "you made it! But you fell x number of times!").
