Wait what does Uchi has to do with it? He was always developing death games/escape room type of vns while this appears to be slice of life drama…
It's not about it being a death game/escape room that's just surface level observation of genre, it's the way the vn is written, as I explained in my comment. The way people talk to each other, the little things brought up, I got into this fresh off of AI somnium files 2 so I felt those vibes hard when reading this haha.
And again, if the author is reading this, I do not mean it in a bad way at all, I'm not saying you're copying it or anything, I mean it as a compliment, Uchikoshi's work is very engaging and I find myself being engaged in a similar way that's tickling my brain in the same way, they may have not even read any of his VNs and it just be a total coincidence haha c:
