There will certainly be some puzzles. The difficulty is to find the balance between making interesting puzzles for those who like it and not too hard/long for those who hate it. Personally I love this kind of gameplay phase in VN, but I know that some people are allergic to it.
For the lesbian content, as I said kinks will be very similar to AF, so there could be a few scenes, but that won't be the focus of the game.
