One more question: are all the sex scenes lesbian/yuri?
Sorry for the slow reply, missed the notification it seems.
1: In the next version I added a bit of improvement to movement and made the dash quicker. hopefully that helps make movement feel better.
2: I don't have a skip button currently, I will look into that though.
3: I am going to add some ways to restore health on events, probably when doing sex scenes at Fawn's new home to match the theme of sex being her 'food'.
4: There is no end to the demo so that you can do the repeatable sex scenes at your leisure, but there is no further content in this version after Necron.
I don't have a specific bug report session but feel free to share any bugs.
Most of the sex scenes currently are yuri, but there are currently three male heroes planned so it will balance out to 4 female and 3 male characters Fawn can have sex with so far.
