Great job with this game and I'm excited for the next update! As for my own personal wishlist:
1. Great job with the current girls, now I want more! Kitty Pryde, Jubiliee, Magik, and Emma Frost are at the top of my list. Hell, you could do some crazy stuff if you go down the Psylocke/Kwannon/Betsy rabbit hole.
2. Keep up the variety in the types of relationships with the girls. You've go Rogue as the sub, Laura as the dom, and Jean as the big sis already which was great. Looks like the tracks are being laid for teacher/student with Storm. If we're going to be entering sophomore year then we can be the big sib with a new freshman character (Kitty or Jubilee). Maybe a "mommy/aunt" figure (Emma Frost comes to mind). Magik could be sort of a Anna/Laura hybrid - tragic past, but more submissive. Dr. Reyes could be a caretaker fantasy.
3. More variation in the female body types. You could have a few petite girls and can even have breast size still be different. Like Kitty could be petite with a great rack and Jubilee could be petite with smaller breasts. Or someone who is small on top but with a nice round ass.
4. More sex positions - Cowgirl, reverse cowgirl, 69, piledriver, standing, etc.
Just a wishlist, but I'll be perfectly happy with whatever the team comes up with anyway. Keep up the fantastic work!
