Lunar Landing Lab (2D)

This 2D companion trades the 3D original's chase camera for a plain side-on view built around the same rocket-descent physics: a throttle control sets thrust along the craft's own nose axis rather than a fixed vertical, so rotating the lander with the left/right controls genuinely redirects where the engine pushes — line the nose up and slow horizontal drift disappears, tip it and the craft slides sideways even at full burn. A gravity-body selector swaps the constant between the Moon (1.62 m/s²), Mars (3.71 m/s²) and Earth (9.81 m/s²) mid-flight, changing how much throttle is needed to hover and how punishing a late burn becomes, while a terrain-roughness slider reshapes the procedurally generated surface around a fixed landing pad. Touchdown is scored on three independent conditions shown live in the status panel — on the pad, upright, and slow enough — so a "hard impact" always explains exactly which one failed.
