The devs main game seems to be earing quite a bit on Patreon it seems though.You're completely missing the point of abandoning a project. The futa/lesbian flavor of the game added interest to it, and it died because the developer is still focused on his main game, which, by the way, having a male protagonist and a bunch of female characters, is still not very popular.
I was always unde the impression the male with a bunch of woman harem was one ofthe most popular themes.
Not for me, though, I'm a big fan of futa and lesbian.
Is a shame this seems to be fully on the sidelines. There is a bit of a futa renaissance going on now though. A few good futa games have been popping up since last year and have been getting decent followings.
