I just played this game and I'm pretty sure I reached all the dialogue and choices!
This game is really well written, with great art. The characters are believable, and the banter between them is hilarious and engaging. There's a great variety of expressions despite the game being on the shorter side, and every mix-and-match between the choices brings new info and dialogue, so it definitely matters which decisions you make.
I'd recommend this game for anyone who likes romance with a side of comedy and mystery! :D
