Is this a real physics simulation or a scripted animation?

It is a real physics simulation: gravity and a tiltable thrust vector are integrated every frame with semi-implicit Euler, fuel is metered as it actually burns, and touchdown is checked against genuine velocity and tilt limits rather than a pre-scripted landing.

What counts as a safe landing?

Touch down on the flat green landing pad with vertical speed at or below 3 m/s, horizontal speed at or below 2 m/s, and tilt within 12 degrees of upright. Miss any of those and it registers as a crash.

How does the gravity slider change the difficulty?

Gravity directly scales the constant downward acceleration in the equations of motion, from the Moon's 1.62 m/s² up to Earth's 9.81 m/s² — higher gravity demands more thrust and fuel to slow the same descent.

The 3D "Lunar Landing" original is one of a hundred reskinned entries in a generic AI-training-arena template shared across unrelated domains (navigation, swarms, logistics, ecosystems…) — its "reward curve" and agents are the same generic goal-seeking demo regardless of title, not an actual descent simulation. This 2D companion instead builds the real thing the title promises: a point-mass lander under constant gravity with a tiltable thrust vector, genuine fuel metering, and a touchdown check against real velocity and tilt limits, so what you fly is an honest physics model of a Moon landing rather than a decorative reskin.
