Hey, thanks for playing the game and leaving a Review.
Yeah, there is an Issue with the Fullscreen, but only if you change that during the Game. If you open full Screen in the Main Menu it should work just fine. But yeah, maybe we should put a warning in the Description for that...
I'm not 100% sure what you mean by going to 4 PM didn't work the first Time. You get the second cogwheel when going forward to 7 AM. When you insert it there and turn the clock back, it stops at 10 PM, which is intended, since you can exit the clock there. But after it stops you should be totally fine turning it even further back to 4 PM.
PS: We may never know what kind of Experiements he did with that Fan previously xD. Great Attention to Detail!
