I'm about to start playing it, because it looks fun and interesting, but before I do, I do just want to point out that the gamma and brightness do not change when you move the slider, at all... (not a turn off from the game, but an observation)
Ok, I could only play for a couple of minutes, because it is far too dark to see anything outside of the projector or circle of light around the chess board. I grabbed the locker key, opened the lockers (struggled to find them) but they are too dark so I can't see if anything is inside of them. If i have to find a flashlight, I cannot see enough for it, and if we are already supposed to have it, F doesn't turn it on... Tldr: Too dark to see, can't tell what/where I'm supposed to do or go
