I like how there's more real-time 3D games popping up lately, makes the gameplay more interesting imo, but I actually prefer the sex scenes to be pre-renderered, it looks way better even without animation.
As for this game, attack animations are very slow and makes the combat feels clunky, framerate is smooth though, which shows the dev put some time into optimization, there's seems to be no interactive dialogues and no story is presented to you, so for now you can't make any choices. It's missing basic features, if you press ESC during gameplay you go straight to the main menu and have to start all over, no save/load.
I didn't even know there were sex scenes until I read the comments, it seems to be one of those where you need to lose to get a sex scene, but even the way it does this is subpar, there's a brief in-engine sex animation and you unlock a bunch of pictures in the gallery showing the heroine's demise, very unsatisfying.
I know it's very early, but at this stage you should at least show what you aim to achieve, if this is it, it doesn't look very promising. I really hope this does well, but it needs to get a lot better. Good luck.
