Ocean in the Cold Sky

You puppeteer your sword's collision in this game with either gamepad or mouse, and you can deflect attacks or dismember your enemies.
A sleepy little machine doll wakes from a dream of the world's end, to a bizarre apocalypse and nowhere to call home. She explores a world of whispering trees, worn paths, deep seas, towering cities, scraped and flooded ruins, and whatever else lies under heaven. Meet interesting characters and murder them, or try to avert their deaths.
The game's levels are generated in pseudorandom chunks, themselves populated randomly with enemies, bosses, friendly npcs, objects, and effects. The enemies have absolute pathfinding ability through these chunks and will roam or pursue the player, while the player's objective is to reach the end by any means be it avoidance or slaughter, betrayal or cooperation.
