Do it or don't. It is inconsequential.Why do I do this? I already wrote that he said on Discord that he was asked by RAINes to test the demo before it was posted. Their collaboration on the new game began after that. The stairs were there before, they appeared at times with Lucy.
I don't care enough to download v1.0 but I don't recall there being a second floor landing in v1.0. I'm talking about the landing not stairs, I think I'm talking about one thing and you are talking about another. So it's really no use continuing down this path as I find it tiring.
