Hi Ray, I've just purchased the game but can't seem to get it game working on Kubuntu 20.04 with OpenJDK 11.0.15. I've played a few other Java games just fine. Tried Update 1b and Update 2 Unstable 2. No window shows and the java executable seems to get stuck at 100% CPU. Logfile at https://pastebin.com/bt1Xg2be
