This World Unknown (itch)

This World Unknown is a fantasy-themed otome game where the player assumes the role of the first person narrator, Rhea, and can romance four available guys. Which route you end up on depends on the choices made during the common route.
The character routes themselves are rather long, and have a lot of plot twists and world building (and lots and lots of characters).
The screen resolution is 1280x720.
