Yar, most of the ingame menu stuff isn't functional at this time. I focused more on the core assets and gameplay to get a single, complete, gameplay loop in before I started putting in the player menu, intros, polish, et cetera. The locked regions don't presently display their locked message, which results in nothing happening when you hit E on them; sorry.
The IG Menu is liable to send the player back to the Main Menu room while saving their previous position and scene to allow you to access options by the WoH-computer desk. I might need callouts for a couple of seconds over those positions just so the player knows that they have to move around the room to access various parts of the game.
Thanks for checking it out and the resulting feedback though. I've added your feedback to my devlist to ensure I don't forget any of it.
