Helen is bugged. occasionally her outfit locks to default and only resets can fix it but eventually, it just ends up happening again, no matter how many times I reset (and I mean this happens with BOTH kinds of resets; hard & soft). not even shutting down & restarting the game fixes it.
it would also be nice to have the option to ask Helen to hypnotize you instead of having to wait for it, which takes a bit.
other than that though, it's an excellent game. I love the different kinds of hypnosis fetishes explored in this game. it's quite a wide range. well done!
Edit:
Aiko's 2nd to last event & Joan's 4th to last event's texts are bugged. the text is duplicated & very difficult to make out. Aiko also seems to be displayed a little too low down in the menu compared to the sprites of the other girls.
