Oh man. I'm so sorry. I have no idea what's going on... I tested it on both my big desktop pc and my shitty laptop and both work fine. Both are windows machines and use windows 10. I don't know why it's not working :_( Can you give me more details?
Ok. Fixed it this time for real. The movement was in the update method so the movement was dependant on the frame rate. What a rookie mistake... Hope you can enjoy the game now :D
