Just played it through (took me a lot longer than 18 mins!) - bearing in mind it's an Alpha so has limited gameplay content, it's excellent.
The artwork is jaw-dropping, you've gone into painstaking detail even in the backgrounds.
I've left a couple of minor bug reports on the Patreon message, nothing serious.
One other minor point is that you can just have all the available 'Fashion Talks' with Prof Seam in one go (so two sessions as the second half need to be unlocked). May be a good idea to string them out, perhaps you have to seduce Prof Seam to get her to help you corrupt Hermione?
She could give previews or something?
Thank you for the comment!
I intended to have a bit different system in the beginning. In the Fashion Talks Galatea was supposed to give you instructions on the order in which classes should be taken and classes would have actual names, not just "Fashion Class 1" etc. It would add another element and it wouldn't be obvious for the player which choice to make. Making the wrong one will cost you time, because Hermione will get mad, she'll run off etc. But I went with a simpler version for now, it was challenging enough to make everything work as it is.
I'm still considering it for the future though, I think it raises the chances to make a wrong decision and gives a bigger dopamine hit when you make the right one.
As I've mentioned in the Patreon post, there will be more classes and teachers, and some of them will provide the corruption element. So in the end you wouldn't be able to just do one class, after a certain point Hermione will refuse to attend it and the teacher will tell that Hermione needs to get up to speed in a different subject first and then come back and continue the course.
Also Galatea will change her outfit as the player progress, first she'll start wearing lingerie for Private Lessons, and then she'll be nude for the Special Assignments, I just didn't have enough time to do it in this version.
