Moonbuggy: Lunar Dispatch

Speed rises linearly with time to 10× after 180 seconds and caps. Obstacle frequency also rises, but every obstacle leaves room for a full jump, landing and another input; close double rocks are removed. Hold Space/Jump for a long jump, release early for short. E/Boost fires and accelerates without exceeding the cap. Armored rocks need two hits. Collect fuel and stay low under beams.
