I have not accounted for small screens, so if you have a small screen you may need to do CRTL & - to zoom out
Only tested on PC and Chrome
Loading performance maybe an issue on the first loading but should be good once loaded
If the game is really slow it maybe because you have multitple screens, I found that an issue at the office but not at home, weird
Enjoy!
