In terms of choice, player choice will drastically influence how the game progresses (which scenes you get, which maps you get, how the story goes), will influence how scenes play out, how Aylia develops (character and skill-wise), and will ultimately lump you into 1 of 6 endings.
In terms of "better," one thing I'm really trying to do is not require a person to corrupt Aylia to see h-scenes. Many corruption games have "virgin" routes, but in doing so, you basically miss out on most of the porn--which is why you're here in the first place! I've come up with a few ways to alleviate this problem. First, there will be consensual scenes where Aylia may just want to have sex (not necessarily in a corrupting way). Second, rivals! I put rivals in place because I wanted someone to get screwed (literally) if you kept Aylia pure. As such, Aylia might stay pure, but that doesn't mean Triste won't get fucked! (Yea, baby!).
As for Bogwort's relationship, he is a huge part of the game. He will be involved whether Aylia stays pure or not, but I'm still trying to give you choice there. Essentially, Aylia and Bogwort's relationship is kind of a whole separate beast which flows down a different set of conditional branches, regardless of other game choices. It is all still in fairly early design stages, and chapter 1 only scratches the surface in this regard, but rest assured, the green guy will get his share of lovin'.
