I found a bug with the Uppie mode's gallery: You can click the option 2 buttons without having them unlocked. Or, at least you can do that with the Body selection, and if you do, it unlocks the 2 options for all the other sections when you do. Also, there should really be an option for disabling the skirt shadow in the gallery like you get in the levels.
I really like the concept of the new mode, especially the fact that we get a more detailed closeup view of the body. But, as another person said, making the skirt go away does kinda defeat the purpose. And, I hope the angles picked for future girls in this mode are more upskirt-y, since as of now, you can barely actually see under the skirt.
