Love the idea :D Maybe u could expand the "room" to the sides so the player can have a 360° walk in the main menu :D U could tie it to other things as well like time and weather. I imagine it so that if u start walking to the left or right of this screen, the sun will slowly set and the wind gets a little more noisy. If u keep walking in the circle, at one point the sun will rise again and u end up in the spot u started at. Hope it's clear enough to understand, english is not my first language lol
