Razuul

You wake up as Razuul, a god who has slept inside your own mind for centuries, only to find a girl named Faja has invaded your planet to kill you. She is cocky, arrogant, beautiful, and clearly did not think this through all the way.

What you do with her is the whole point. You can kill her outright, play with her, talk her into trusting you, try to date her, or earn that trust just to betray it later. There are hints she isn't quite as simple as she looks, and that the threat might run both ways.

The game moves through that choice rather than a fixed script, letting your reaction to Faja shape what she becomes to you. Given the setup, a god and an intruder who invited herself in, expect the encounters to lean into groping, harassment, and monstrous, tentacled excess, vore included, with the size and power gap doing a lot of the work. This is an initial zone release, so it's the opening stretch of that story rather than the whole thing.
