no no no! Collecting coins should not move you back that is so frustrating haha :)
I got past a few of the enemies (I assume they were enemies) I hit them with a stick and they disappeared! Come to think of it, they weren't attacking me or being agressive... oh dear god, what did I do.
Nice concept but the controls need some smoothing out. Also if you continue this game, add some animations to the characters so they are less static. Maybe add some different coloured coins that do different things like teleport you forwards or give you abilities...
