Prioritise safely delivered cargo, predictions with units, and an explanation of the result. Simulation time becomes a tie-breaker only after a valid delivery.
Build the next delivery.
Play the Lift Depot: three delivery puzzles and a level builder →
Predict. Run a measured experiment. Inspect the result. These working physics models prepare the next puzzles, without changing the two existing greenhouse routes.
READY
This is a schematic physics workbench, not a finished cooperative level. One simulated clock, SI units, g = 9.8 m/s². Pausing, editing, tab hiding and losing focus pause the experiment. Playback speed changes viewing time only. Inputs and checkpoints stay only in this tab.
CAMPAIGN BLUEPRINT
One idea at a time. Then a chain.
Stages 01–02 already exist in the greenhouse. Stages 03–09 below are specific designs. A working workshop model is not yet an integrated playable room.
Keep the game honest.
Operator, observer and caller can share one plan. Solo play programs the same stages. Crew count changes available controls, not hidden physical constants.
Rope, spring, latch, coupler, motor and bumper forces must come from the model. No automatic stop, impossible catch or reset disguised as physics.
