I liked the art, Bozu had some funny faces especially, but the other characters were nicely drawn as well. The CGs were pretty good, too. The story was also kind of interesting, but I had a bit of a hard time following it in some scenes. This was partly because you seem to have forgot to set the character name field correctly on some dialogues? (sometimes there's even dialogue text in the name box) Aside from that my biggest complaint is probably Hanako's memory scene being so brutal compared to everything else, but then I'm not a big fan of horror myself ;;
Overall good work with the game!
