Marscraft

Prompt

Create a 3D voxel game called Marscraft, similar to Minecraft, but it is set on Mars, specifically the classical sci-fi version of Mars (with Martians, alien life (alien mobs like space cows, space octopi, etc., there should be a variety of different mobs, including mobs in canals) and plants, canals, two moons and Sun in the Martian sky, day/night cycle, sand, lava and water physics (lava flows slower), red landscape, caves, alien structures and villages, etc.). Implement mining, crafting (with a wide variety of craftable items), fall damage, fighting, block placing, item dropping, glass, health, oxygen (but oxygen should deplete only under water, the atmosphere should be breathable), hunger, eating, sleeping, inventory. The game should have infinite procedurally generated 3D terrain, with bedrock in bottom. As bonus you can also create different biomes (like normal plains, sand dune desert, volcanic fields, glaciers, oceans/lakes, alien oasis (with some strange vegetation)), portals to Venus (hell-themed, you can imagine something between Doom and Minecraft) and Titan (frozen with methane lakes) (so other worlds), with different biomes/worlds having their specific mobs. There should be both friendly mobs and monsters active at night, in caves, or in specific biomes/worlds. Do not use emojis. The game should be complete, functional, impressive and feature-rich.
