As of playing (Mostly) the whole game, I'm honestly not sure what my feelings on it are so I'll leave a neutral rating.
The art itself is very cute, albeit a little rough, but it has charm to it.
The story is very mixed to me, the good and true ending were definitely emotionally impactful but the dark/bad endings (Which I could only find 1 dark end and there's no guide for that) were...I want to say edgy? 

Or maybe that it feels predictable and cliché to have the mentally ill character go full-on violent murderer?
Either way, the immediate plot twist makes the reaction of all the characters very obvious, though that may have been the intent that the audience knows that only the MC doesn't know that everyone else knows but we know...ya know. (Sorry, bad joke)

Anyway, I had to use a guide for the good ending and was confused by the LGBT tag the rest of the game, but noooow I see. (I guess I expected it to take up more of the game, but that's fine too. I had thought maybe it was meant to be implied that MC had a romantic love for Aoi, but due to the vague nature of the word love in English, I can't be sure.)
