Exit Foundry
Cool TWO copper crates in the blue quench bath Q, then push each into a furnace F. Hot crates cannot enter furnaces. Walk with arrows or tap an adjacent cell; pushing moves a crate one square. Once both furnaces are fed, the bottom-right exit ◆ opens. Walls block movement, and crates cannot be pulled, so preserve space behind them. Undo reverses a step or melt; no automatic defeat.
Controls & scope
Tap the board or named controls. Tab and Enter/Space operate buttons; R restarts. Undo supports reversible planning; no automatic defeat.
