Purchased this on Steam before I realized it was available here. That's my only complaint. ;) Easily the best casual hentai I have ever had the pleasure of getting my hands on. Also probably the only reason I even looked at Wet Nightmares, which isn't my usual genre. You should consider more cross-over material as future games release. It certainly worked on me!
The "Titter" mechanic is what really stood out to me. Great way to highlight each girl's personality. (Guess it helps that I also really liked a lot of the personalities.) I think someone else mentioned that it adds pressure when building a combo, but I did one playthrough to focus on the conversations and a separate one to focus on speed. Worked out nice for me.
