I'm sure it's a nice game, but it's always a risk with any Unity game, because you can't get custom resolutions to stick. Launch parameter command lines do work on "some" Unity games, but it doesn't stick with this one. Lost in Vivo has the same problem. Changing areas or a loading screen the display flickers and it defaults to whatever the dev has set internally. Changing resolution in-game switches to windowed on confirmation and while using ALt+F4 does work to switch to fullscreen, it also defaults the resolution.

My short and sweet opinion: absolutely abysmal stealth mechanics. I think it's a cardinal sin for horror/thriller experiences to root the fear entirely in the helplessness of the protag by giving you no defense and making you sneak around at a snail's pace hoping the copy-and-paste block of code doesn't turn around and make you reload a save.
