Synced 2026-09-04 from commit 82e211b.

No change notes for this version.

One simulation, two gravity fields. Suck up material, sell it, buy a better vacuum, and expose 75% of the bedrock to win — through ice, clogging wet sand, and dust storms that blow your pit shut. Every upgrade changes the physics rather than a number on a panel.

Controls

  • Drag on the canvas — vacuum
  • space — pause
  • r — reset
  • w — add water
  • p — toggle the pump
