I can't believe you've finished this game within 24hrs! It's sooooo good and I didn't encounter any bugs. The story is something I liked too - Yokais, spirits, myths, history (I'm not really sure what you call it XDD, maybe Japanese literature?). I've been wanting to play this kind of game/s since I've only been reading them in mangas. >.<
And, I laughed at Jun's fishy memory. XDD
Oh and I have a playthrough of the game, I hope it's okay! Here is the link:
Keep it up!!!!
