Lean Into the Swarm is a single-screen incremental game about consuming an entire world. Your harvesters work automatically, clearing trees, rocks, and stranger materials tile by tile. You decide where the swarm moves next, when to use Scorch, and which upgrades are worth buying before the world is gone.

Every cleared tile feeds the next purchase. More harvesters and stronger tools speed up the process, while depletion and regrowth change the shape of the frontier. Once enough of a world has been consumed, you move on to a larger one with new resources, colors, and costs.

World jumps award Salvage, which is spent on permanent perks that carry across the run. The full run covers sixteen worlds. There are no offline earnings. Progress happens while the game is open and the world is visibly disappearing.
