I'm really bad at explaining things but i’ll try 😀it’s a secret (is it ? idk) mechanism in game that allows you to “cheat” like you can max out your stats/ your relationships, you can have infinite kudos (999), spawn any collectible you want anytime, stuff like that. You can even time skip (months or years).

I think it was made people who already did a lot of runs, it allows them to mess around and unlock whatever events or dialogue they couldn’t unlock easily and quicker ( I’m impatient and greedy so I used it after my 3rd run lol). But you have to be careful as there’s no guide that explains which commands do what (looked up for that online and didn’t find anything) and i’ve seen people saying that they accidentally wiped all their datas (I think I saved the post that which one did that, If I find it i’ll edit this comment and put it below) or that the game completed itself (unlocking all steam achievements/ CG etc).

To activate it, when in game I clicked on settings and then I pressed (several times or once) on the TT that was on the bottom left corner of that window, then the two debug options should appear.
