Your game is very cute. I like the choice of music, but it'd be nice to make it loop because if I stay in an area for too long, it will end at some point.
A problem I had was that I can't buy the gear, the guy wont take my money T-T
Also, hitting an obstacle stops all velocity in that direction, and when trying to hit the skeleton, the swing animation doesn't always show up.
Overall, you have a nice game, good job!
