Hey! Thanks for playing, while the arms not reaching the buttons is actually an intended feature (For the selected ages of 1 - 16), the screen size however is not! Could you tell me the size of the screen you were using?
I was unaware of the fact that age was what effected the arm length. I assumed the collision borders might of changed with the screen size but I think it was actually the age system. Thanks for helping I'll give it another shot.
Edit: Finished the game and loved it. Nice job! :D
