I thought the same for the longest time. I blame playing tons of runescape as a kid.
I am an American so mold spelling is definitely what I ran into when referring to the fungus. Runescape is British English, so you used moulds all the time in crafting.
I’ve always heard it described as Minecraft meets Primitive Technology. I would say that is quite accurate. Maybe some (optional) Don’t Starve like elements where you have to worry about the temporal rift (sort of like insanity) and drifters (largely at night).
Technology progression is much slower than Minecraft. Also much more involved. Want a stone axe? You have to place a stone on the ground and use another stone to knap it into shape first. Make an iron shovel? You have to heat up the ingot first and then beat it into shape on an anvil. If you are too slow and it cools down you have to heat it up again.
Farming has 3 nutrient groups, so fertilizers and crop rotation is important.
Leather making is a multi step process of soaking hides in various liquids.
It has a built in and very extensive guide/wiki. It also has a native Linux build.
To my knowledge that only works for the 2021 version which is no longer sold. The newer 2024 version is locked down further and cannot have its bootloader unlocked.
