Dear developer, configuration window can not be minimized. I went to sleep and then screen say day ? +2 and then i put all nutrition boxes to toilet and then i flush toilet and then i fall and appear in black room and i could not figure out. I think i found bug. Also i can not set graphic quality in game. I can not set vsync. I can not set antialiasing. sounds are missing. I can not pause game with esc button. Playstation 3 gamepad was not tested. I can not run with shift button. I can not crouch with ctrl button. I can not jump with space bar.
