I wonder if it would be fine to have items which are already available in the game as rewards. In theory, there isn't a big problem with adding new weapons and armors (although it would take some time to consider the balance and to think about what would make sense as a gift from this or that character), clothes however are a different beast, since I only ever use them to unlock unique scenes (due to how the game was coded, it's extremely awkward to add a clothing system now), so those are probably off the table. If we were talking just about a memento/gift, that would also be pretty easy to do (obviously).
Yeah, there were plans for a werewolf quest, but it's getting cut at this point (might be something to add if I eventually revisit the game in the future). At least the alpha stuff is acknowledged in the ending, and you do get a bonus in battle from it.
The H-scenes list is missing a lot, and I am also getting ready for my next game. While you can expect me to make progress on that front, it won't be completed quickly either. It's the problem with one-man projects like this one.
Thanks! ^_^
