Not interesting in the least, I jumped Discord one time to see what OGRey was doing with his game.It's interesting that you remember stairs and not remember what OGRey wrote himself (in Discord), probably your attention is very distributive...
I browse through some pictures read some messages and never went back on there, so whatever OGRey wrote about his involvement in the demo I have no clue.
All I can tell you is I remember seeing the up stairs landing picture on OGRey's Discord server, so his involvement with the demo is more than just mere testing of the game code.
You sound like you are on Discord, you can just ask OGRey about it.
