I just bought this game and installed it. Ofcorse, i tested the "Settings" InGame first. So i switched from FullScreen to WindowedMode. The Gamewindow went black. Now i re-clicked "switch to FullScreen" (while the Gamewindow was black, but i could hear the "click"-sound". The black window went fullscreen, but it stuck black. So i killed the Game with ALT+F4 and restarted it. Now, the game keeps beeing black and i dont know, how to solve this. Cant find any config-file, to maybe fix this.

Any Idea, how to solve this?

/cheers&thanks

I solved the problem, after do some research.

Simple delete following folder (incl. all subfolders/files):
/home/USER/.config/unity3d/Ekuator Games
(WARNING: Im not sure, if this will delete savegames, since i didnt played it yet.)
