This game is perfect for android/iOS platform. You guys have what it takes for a popular piece. Nice job! My suggestion: make the in-game screem larger (smaller character, coins, enemies, pwps), like a 16:9. This could allow the use of less detailed textures as well, making it smoother.
You spend months working on a game to simply forget a Mute Music button? You know, some people would rather listen to their computer's music instead of your game's. Nothing personal.
