#kerbal space program
It was a game similar to kerbal space program in that it was about making and flying spaceships. Everything was normal until they left the atmosphere. Space looks like it had been razed and the starting “planet” was a vaguely stalagmite-shaped shattered chunk. The top (where the launch site was) was a piece of the planet’s crust with the bottom having some kind of space station-city hybrid and one of the sides was lush and green, seemingly having grown on after the shattering. The vessel then flew down to this place and landed in a river. The area was a thick rainforest with deep, wide river networks that streaked on for miles. In the river were dunkleosteus and giant wobbegongs that could eat the vessel whole. Also the moon was another, slightly smaller chunk.
cool as shit
