I just played this "demo" for the first time, never played Dominatrix Simulator before. And yes, I played it in VR with a decent "room setup". I'd like to preface that I'm not at all into BDSM/sub/dom stuff, but I always wanted to test this out because there's still a lack of "good" VR adult games.
Sorry to say, but I'm NOT impressed at all. The models are low poly, the "animations" are very rough with a lot of clippings, and although the devs claim that "all of our models [...] are custom created" they look very familiar and are to much of a "Hentai" kind of style. I am not saying this is another cheap MikuMikuDance rip-off with the addition of some custom made assets, but it reminds me a lot of other games like Waifu-Sex-Simulator (which I supported a long time on Patreon until I got tired of its style and lack of new content).
I know this is just a demo, and there will be new stuff added to the game. But without more realistic looking models and better animations it's just not the type of game I'd like to play or support. I wish the devs best of luck with their game, I'll give it another try in a year or two if there's actual content I (may) like.
