Writing this as I finish my first playthrough (with a bad end!). I genuinely enjoyed getting to know the characters through the chat (which made the bad end hit all the harder) ++ delighted in the depiction of the parts of fandom that brought the characters joy. The story also didn't shy away from tough topics (tw is accurate!). I felt very unsettled at one point in particular and that's totally a credit to the writing + characterizations.
Edit: Ok - the choices are just tricky enough that it took me several tries to get the good endings for all of the routes and I did have to check the walkthrough for xyx. When I get bad endings I can't stop/won't stop trying again so I absolutely did marathon the game. :)
