I noticed with the last update that the title has that "lacking" feel. Continuing from my last save, It felt odd and was missing that spunk I loved from Harem Hotel. I honestly though because of how old my save was and the new update, the game broke. I'm happy to hear that you are looking into spicing it back up!
I do have a couple of quests. In the current version, misc info shows a ! for Jin but cannot get her to do anything. Try different times of the day and even tried roaming around and it just stays the same. I saw the score for her was 5/10 so that tells me theres interactions missing.
Any chance for a hint system? Like something that tells you what girl needs what to advance her line? (would help for the previous issue one paragraph up)
Lastly, will there be any naughtiness with the faires? Stuck in a room with a nympho girl could have brought out certain curiosities!
