I loved playing it! Very addictive and great challenge!
Oh, I'm sorry that it isn't working for you!! When the voting is over I'm going to have to properly figure out how to build games and get them to the right resolution etc since this was my first time! Sorry for the inconveniences :\
Are you playing in fullscreen? That may be the problem with it
You may need to refresh your browser, try that to see if it works, if it doesn't let me know :)
