Okay the game is kinda fun! I see you fixed that no decisions bug so it actually works and I think I was just dumb earlier reading that closing the door decreases your sanity. I also love the pixel camera and the flashing lights, they make everything look a little bit scarier.
Though I don't really like the fact that the decisions are don't do or do, as just not taking them will basically not change anything and will be the best choice in most circumstances. It would be a whole lot better if there was a choice between 2 decisions, as then both would have a risk attached to them.
Also the death screen comes really suddenly, maybe there should be some kind of an indicator just before dying like if the oxygen is running out you get a blue vignette or purple or read if you are going insane.
Also now you can spam through the paper in the first quarter of a day and then you just look at the walls if there's danger or you have to open the valve. Maybe the decisions could be spread out through the day so like you don't just spam through them all at the start.
Though overall a great concept and with some polish it could be really good.
...I also spent like 7min trying to get zalgo text in to the leader board name, but I see you blocked copy pasting in there, even the emoji keyboard didn't work (though idk if that just uses copypaste functionality or something like that too).
