Hey. I tested your game and its pretty fun to play. I would suggest changing following things: - swap REPLAY and MENU when you die (so replay will be more accesible for right tumb (main thumb))
- add more features to background ( maybe birds or sun mountains etc.)
-when changing dificulty you can make GUI more
- watch Jonas video (Why your platformer sucks) and add delay to junping. That will improve gameplay alot.
Good job.
