I'll also add other things that I have encountered on my last playthrough.
The bug with the loss of the gallery is also there when I reload the game with a difficulty other than "normal" (maybe because it goes back to normal, but that way, we could never complete the gallery, because we won't have all the endings, as we have to reload the game to change the difficulty...).
At the end of the tutorial, the "Clock in" button appears at least 30 seconds after the last word of the boss.
Just something that I think could be better, maybe you could add something to let us know when we have made a bad choice, so that we can improve ourselves. For me it could just be a buzzer sound or something like that, it'll be enough ! (I don't know if it's possible or if you want it, but that's just my opinion!)
Have a nice week!
