Thank you so much for your kind words! I took a look at the coding and it seems to be an issue with the way the counting works. I believe it happens during the kiss option menu, I forgot to have the system give a point when you actually do end up choosing the kiss option. Getting 8 does not unlock anything else however! There is only one hidden CG and that is the puzzle in the journal once you unlock all the pages.
Thank you again for playing and I'm really glad you enjoyed it!
