The game is pretty solid, but i still prefer STD more from a visual and mechanical standpoint but aside from that, the game has currently some visual bugs across the board, the missionary position looks very awkward and im not a fan of the face shape/customizations. The animations are quite stiff, sometimes the characters parts "break apart" where there are visible gaps at the legs, throat ect.
Its a solid game, but i think it lacks some mechanics that the default STD came with naturally, and i hope the game will be improved upon.
Aside from that the game has a fantastic foundation to do what Kasumi Rebirth and Tifa sex abuse did, if there would a front-view and you could fiddle and do whatever with the female character that would be an absolute dream! But that's only a suggestion ^^
