Inherit the Kill
A turn-based dungeon crawl on a single fixed 12x12 floor. You start as a lone adventurer with three hearts. Move onto an adjacent orc to attack it. When an orc lands the killing blow on your current body, you instantly take control of that orc instead, continuing the fight from its position and remaining hearts — your old body becomes a corpse. Reach the stairwell tile in whatever body you are currently wearing to escape. The floor also has two trap tiles: stepping on one costs a heart and, unlike an orc's killing blow, ends the run immediately with no body to inherit.
Controls: arrow keys or WASD move one tile at a time; moving into an orc attacks it instead of stepping onto its tile.
