Dev listed future tags, anal isn't in there. Doesn't bother me, but it seems there's no sexual content in chapter 1, so I'll probably just wait for chapter 2. Dev probably should have waited until they had a little more content to show before releasing the game.
A chapter 1 release with only 209 renders and no sexual content after 6 months of development is not a great indicator for the future. Also, with so little content, charging $21 on Patreon(super risky with incest) just to get the updates on day 1 seems rather greedy. If the updates all end up taking 6 months, and are of similar size, that's basically asking people to pay $126, and wait 6 months, for each small update. Dev is asking for the equivalent of 4 AAA studio games per year, just to play 2 small updates of a generic and small AVN.
