I have really tryed opening this game but I am failing, I even got it to the jav file but nothing. I installed Java from oracle but noting. Anyone got any tips? Any would be much appreciated.

you don't need java, you can download windows version, unpack it and just open . exe

on Mac it's a bit more tricky, but still you don't need to open it with java

yeah I tried that and it got out of hand, I have tryed like 5 methods
