Thanks for the feedback. hmmmm that's strange. I've develop the game with the xbox 360 controler in mind (i own one myself). That happens both on the browser and .exe? What's your OS?
Yeah, I just tried both and had the same problem and I'm on Windows 10. I'm not sure if it would make any difference but my controller isnt an official xbox controller, I've never had any problems with it before though :/ I cant connect my official ones to check though
