Scripted main menu?

[Romulator]

Oh btw, is there a possible thing to ADD new keys?!
Like I know we have some several keys to move etc, but is it actually possible to add literally new keys?
I would like that, because if that is possible, I can actually make An easter egg where the player can " play " on the main menu by clicking or typing several things.

No, you cannot add new key inputs to Amnesia. The best thing you probably can do is remove the flashlight and use the F key.
