Something that really makes me uneasy is how much development time is still left. Each update is taking at least two months to complete, and there are still three updates to go — Lyly’s side quest (currently in development), then Haylen’s, and finally the main quest 29. That alone would be about six months.
Now, there are three endings (with two possible variations for the NTR ending). Based on the amount of expected content for all the characters, I’d estimate each ending could take around 4 to 6 months of development. That would mean roughly 1.5 to 2 years just for the endings, adding up to around 2 to 2.5 years of total development for what’s left of the game.
Of course, these are just my own estimations based on N_Taii’s usual update pace — I don’t really know what his projected timeline looks like for finishing the remaining content.
