Nice! 2 problems I found were that sometimes, the cubes would get stuck on the edge of the machines and another thing I noticed is that when you pause the game by going in the options, the fps counter glitches out.
Good, one issue I found was that if you are pushing against one of your team (Ex: Rock) and they get turned into the opponent (Ex: Paper), you can still continue to push them without turning into them...
1. If you press escape on the browser version, the game gets an error.
2. When I pressed the final exit door again and again, at one point, it stopped updating the transition so it would keep showing the same image instead of yor current view.
