I thought this was pretty cool. I grew up with a very distant view of RM2K communities, and now find a lot of enjoyment in reading blogs and LPs that cover the ins and outs of projects I saw or heard of in passing during my RPG Maker youth. This reminds me a lot of those kinds of partially-concrete, partially-intuition analyses, so I think you did a great job with it!
Sitzprobe kind of reminds in part of OFF, mainly like the friction between two main characters and taking place in sort of an abstract place with like, abstract/symbolic dialogue, I guess. If it existed, I imagine I would play it through, take in all the vibes, then chew on a bunch of analysis by people a lot sharper than me XD
