This is probably the wildest move I've ever seen a porn maker do. There is such a loose connection between people who loved their previous work and people who - for some reason that science absolutely cannot explain - want a shitty 3D game whose only distinguishing feature is a girl running around naked and maybe clumsily fucking some fauna at some point, that it seems insane to even attempt this leap.
Its much easier to milk subscribestar money month by month with a game than animation. Say, with an animation its just "I'm working on it", "its delayed", "its rendering", "heres one picture update, be happy". With a 3d game, you get those mentioned AND MORE, like "I have to bugfix", "I don't know how to game dev, brb, I got to learn this thing to game dev", "we need more money since its bigger than just an animation"
Instead of fapping with dick in hand, I have to WASD, click puzzles, collect stones to put in sockets, backtrack™...no saving btw, if you fall through the floor after 45mins of "gameplay" 90% of the way and miss the one last animation for the update, good luck wasting 45mins again. Be a good boy and sub again for the next update in a year for 2 animations this time.
