For an initial release I see this much like the back of a book's cover. So far I'm interested in the story. The thing I'm most worried about right now is if combat will actually play a role in the game. I don't think simple dialogue choice boxes like the ones used in the sex scenes have ever worked very well in a VN of any sort. It would be nice to have some sort of combat system however, so I believe a game to take some inspiration from in that regard is Raven's Quest which can be found on Itch. I don't know what other things the game is planning to add but I would certainly recommend taking some pointers from the game I mentioned earlier. My final ending note is a suggestion for an already incorporated feature, sex scenes. It's not bad at all, but I think it could use a bit more flow to it. I think being able to select the five scenes all at once and having them play in the selected order without pause would be a simple yet powerful improvement for future opportunities.
I know I mostly talked about things that could be better so I figure I emphasize one sentiment. The game has a great start so far, I hope it's still great by the end.
(Also thanks for compiling for Linux!)
