Polygon: "The Swapper is a slow and thoughtful game unnervingly fixated on its gratuitous death toll. It's a puzzle game that asks you to consider your actions, both literally and mentally — what they did and what they cost. It is the space marine shooter inverted. Its antagonists are immobile, talkative rocks; its environment is static and action-free; its sole weapon only kills you. And The Swapper is a fantastic puzzle game because its best riddles are the ones that can't be solved."
