Hey im currently playing your game. While I haven't finished it yet I want to say it's very charming. It has a homebrew type of flavour I enjoy a lot, seeing the anime screenshots in combination with RPG maker engine cutscenes is pretty cute. The RPG combat itself also is surprisingly balanced so far, I didn't expect to see a optional boss either. So far my playtrough has been Rika and akasaka.
Something im curious about is is the dialogue taken 1:1 from the VN or Anime? I played the VN in Japanese so I'm not aware if that's the case, but in case it isn't the writing seems pretty solid and faithful regardless so far. If you were to ask for some honest criticism then I suppose that stuff can feel a bit rushed? But I understand there's not much appeal to run back the entire original story/not getting to the puzzles fast in a puzzle chapter. To which I gotta say though I really liked that aspect of rikas chapter. Makes me wanna replay rikas chapter to see if I can find kenta-kun!
I hope this feedback has some value despite me not having seen everything just yet.
