This game definitely could be pretty damn good if those bugs and errors were polished out. I doubt it will get an update though considering the last one was in 2021 and the developer clearly moved on to other projects. One can certainly hope though.
Also, if you click on the journal at home and click on the girl's icons you can see their story parts and replay the scenarios to see their CGs again. Obviously an actual gallery would be better for viewing but it basically does the same thing, gotta deal with text boxes though. :\.
