For a first version there sure is a lot of stuff, nice. Will this be more of a harem game, or more like Visual Novels with specific paths for each girl? Personally i'd prefer harem cause usually for these hentai games i'd rather go with everyone than having to choose, but ultimately i accept the vision the dev has to make the story flow.
Regardless, this has the potential to be one of the best free koikatsu-style hentai games on Itch, alongside Corrupted Kingdoms and Goddesses' Whim.
