I have an Intel Iris Xe graphics card. The game is so dark it's impossible to play, even though the brightness is set to high. How can I fix this?

I couldnt move or look around i was bugged stuck for good and had to exit the game and restart all the way from beggining https://www.twitch.tv/johnnyghostron/clip/ScrumptiousTangibleNikudonPeteZarollTie-zMfXOogI-2kBq21T

When i change key binding config on settings menu, then go back in game, default binding remains active.

How can I get the achievement for Lights Out, Tiny Memento, and Mind Glitch? I've been going around all the levels and there's no way to unlock it. Please, if anyone knows, let me know.

Just curious but how does the save system work in this game?
