I'm one of his patreons and I can tell you why I support this game:
1- I like the story of a couple alone in a desert island.
2- I like a slow and steady progression in opposition to a fuckfest game.
3- I enjoy some taboo themes, this game is about incest (you like it or not, so the game will treat her as the MC's daughter because that's what she's supposed to be)
4- I love the graphics in general and I find the main female character very attractive.
5- Developers deliver an update regularly.
6- The quality of the updates vary from good to great, just one update I would rate as poor (the one with a fuckfest outside the island)
7- For me, together with 'Babysitter' it is the best game in development at the moment.
Totally agree. I'm a patreon too and for me he's doing a good job.
The point is, if you want a fuckfest with D, well this game isn't right for you.
Maybe in the future the level of hard core will raise,
but for now the developer it's quite good in create sexual tension and expectatives.
And, yes, that's the most interesting part. Tension and expectatives
