what a cool experience this was, there are so many hidden nuggets of charm in this seemingly isolated world that i'm not sure if i was able to uncover it all! this is walking-sim in its pure-essence, just moving around and taking the environment in. the experience in of itself felt so surreal, but not overtly to the point of being too cheesy about it. there were so many neat things in the game, some of the obvious ones like the objects in the apartment and the radios (seeing those always gave me a smile xd). then theres even just these small weird things in the game like the fact that you can double jump, the holes in the buildings which allow you to see through the non-back face rendered buildings, and this one random door that you can just open in the apartment building (i thought i was gonna get jumpscared, was about to throw hands).
really loved the presentation of the game! the low res aesthetic works so well with the models that you created and laid out! that grassy field looks absolutely amazing, i stood out there for a good minute watching it flow through the wind (and hearing it too xd). the restraint in the use of colors against your mostly desaturated cityscapes adds a lot to the visual intrigue to the game. also a nice contrast to see the more rural and town-like area have at least patches of color here and there while crossing the bridge to the city leads you into an area drained of color full of black and white, with the grey towering building at the center of it all! even in the city parts and the buildings in the background, its impressive how visually appealing you can make these parts of the game just on arrangement and good shape language alone (especially in the city backgrounds), its very nice to look at!
overall, what a weirdly cool exploration game this was! you mentioned something about the manga shimeji simulation, which i haven't heard of before, but i do know of the mangaka's other work "girl's last tour", which captures the essence of beauty inside of an isolated dying world super well through the appreciation of these small humane moments and blips that we encounter in our lives. this world shares that same energy which is cool to think about! thanks for the manga rec, great work!
