I'll fill you in on the gritty: As of now, there's some light BDSM. I intend to do a rather intricate cuck scene in the future, allowing the player to jump in the role of Austin (the cuck) or remain as MC in that scene. Also intend to have players wake up in the role of MC's sister for a segment, but that's way down the line.
I'd say this has a bit more game to it than SS (I'm biased, lol), but the art isn't as polished. That's something that would be addressed if we can ever get off the ground.
Here's the last trailer I made if you haven't seen it, though I should update it. Some really cool stuff coming out soon.
