Gravity Foundry

Safe rehearsals plot the actual trajectory before committing a launch. A lunar chamber halves gravity and relocates both targets, making mass, propulsion, elevation and blast radius a new design problem.

Assemble a projectile from three sockets, set its launch elevation, and test whether gravity and momentum carry its blast through both targets.

Tap or click the controls. Keyboard: Tab and Enter/Space operate every button; arrows/WASD move where available, R restarts, Z undoes calm puzzles.

This challenge has reachable failure. Restart returns to the same fair opening.
