Sorry I couldn't get far in the game. I kinda can't because of the only handful of issues I noticed.
1 - The browser version just didn't want to work. Not sure if this is just me, but it ran worse than the Desktop Ver, and it didn't lock the mouse.
2 - There's no Windowed Mode on Desktop.
3 - The pause menu (G) only displays status. There seems to be no option to exit the game while playing.On top of that, the pause menu requires the player to look at it manually, so if windowed mode were added/ mouse lock fixed, it'd be impossible to close the game that way.
Those last 2 issues make it impossible for me. I don't live alone so I need a quick way to close the game in case someone decides to all but teleport into the room I'm in. My suggestion would be to have the escape key immediately close the game.
