I think a cool addition for this game would be different mushrooms native to different planet types that only grow over time in certain conditions.
For example, say I live on a Lush Temperate Planet. The planet will spawn say a “Redcap Mushroom” (used in recipes for food and brew) that only periodically grows in a moist, spacious cave. The game would only spawn the mushroom in enclosed areas of rock that had pools of water within 15 or so blocks. If I want this mushroom, I either have to go exploring caves or I have to make my own mushroom cave farm.
Another type of mushroom might only be found underneath the trunk of a specific tree, another might require high heat and only grown near lava or fire, etc etc.
I think this would work well because it would add more depth to the game, would encourage more exploration and more portal management. Imagine finding a jackpot of rare mushrooms deep in a cave and making a private portal there.
Thanks for listening!
