So there is a Minetest-gamemod “Moon Test” which is a lovely experience in itself but in thecurrent stage of development it is a bit pale. Mobs and other “creatures” would been awesome. Unfortunately, my codingskills is not so well developed (and 100% self taught). They is right now made up my by me tinkering the code to the existing mods and see what happens. So it takes a long time and the result is not always so good.
What I‘m good at is to draw and create. So I made a skin for an undead cosmonaut so when someone will sit down and write mods to the moon tests, there is one already. I’m thinking about making small robots, and might get me into the fight with Blender again. But we’ll see.
