Thanks!
I did it for the epic JAM in 3 days so I couldn't finish many details, thank you very much for the feedback! were you able to finish the game?
I can give you a hint, before starting the game, in the controls part, you can see that there is a button with which you can examine things, the code is in that same corridor and quite visible
The key is held by a hand, at the end of where you fall, a little before the fire
