I'm using the Mac build and this confused me for a second https://prnt.sc/ssaj6l. I justa ssumed it was a joke and the game will explain it after words but nothing happened. I checked the game page here and the controls weren't listed as well. It took me a while to realise it was the SHIFT key. The game lore seems pretty cool, but after finishing the first level after the tutorial, then it teleports me to a room with a half covered picture, then the level repeats. I assume that the game in incomplete, and if that's so, it would be pretty cool to see the whole story.
The time stopping button could be replaced with some like Q because it'll be easier to control.
