It was a fun mystery game! I like how we can read back the clues we gathered and think more about it before the big reveal! I actually did solve who killed the victims even before the reveal, even though I didn't know the exact who www Love the characters and their design, especially Mio's kasa-obake costume eye that moves and has its own expression, it's cute~(´▽`ʃ♡ƪ)
Although the mystery itself is good, I didn't particularly fond of the ending. It felt awkward for me, with everything happening but the bad guy still hung around, just like that? Maybe it would be better if the bad guy just escaped or vanished dramatically into the unknown, and then the helplessness the survivors felt could be explored even more.
