Are you playing on a phone/tablet? If so what one? Do you know the resolution?
Or are you playing on PC? If so whats the resolution your computer is set to?
Thanks for the feedback.
Resolution issue is the first thing I plan to fix. When I originally made it I was planning on making it a mobile app. I learned I could post the game to the web instead so I just tossed it up with zero changes to the code.
A temp fix to that may allow you to play on Mac is to set the game to full screen.
