Great concept, the clicking of the coin to make it flip was hard to tell if it was flipping or if I didn't click it. It would be cool to see that polished some more but otherwise I liked the use of the mechanic and theme!
Ive updated with improvements on player movement, UI and 1 level more, added some sounds too! (I didnt know that I can update it before ratings ends :D ) working on next 3 levels :)
