Symbiosis Overgrowth: A plant post-apocalyptic Voyage

Your in the middle of everything in a ruined, overgrown metropolis. The world ended in the Verdant Cataclysm—mutated plants and beasts reclaimed the cities, leaving survivors to scavenge amid acidic rains and hostile plants and mutated wildlife. The world is a decaying concrete labyrinth reclaimed by an unrelenting, hyper-evolved botanical force. Beneath a sky of perpetual acidic rain, the city exists as a vertical ecosystem where structures are colonized by predatory flora that treat biological life as fuel. Survivors operate as desperate scavengers within a closed-loop biomass economy, caught between the encroaching mycelium hive mind and their own struggle for resource efficiency. This post-apocalyptic survival world contains environmental horror and predatory plant threats but presents them as gameplay systems rather than graphic depictions. The world describes sentient plants treating humans as "biomass," acidic rain erosion, and survivors forced to scavenge in a hostile vertical jungle. However, the content focuses on resource management mechanics (biomass harvesting measured in decimal units, facility upkeep costs), environmental hazards as stat effects, and faction survival dynamics. [Featuring a 'Custom Made Biomass system interface' for buying and creating stuff using units of Biomass.] Might be easiest to use this system by talking through the narrator chat in a logical way to use the biomass to get items, traits and what not to survive or improve yourself. This system will be a large part of the game as it can be used to tame/control mutated plants as minions/followers for biomass upkeep. Credits to '@cubile oddity' for the shop system. [Experimental Voyage adventure based on a AI random Story I found on YouTube that I thought could be fun here as an adaptation. Enjoy and Share of your mishaps or adventures ;) ] Disclaimer: "This is a work of fiction.

Changelog: [Initial Draft] Basic plant apocalypse storyline based on a YouTube AI made story I thought would be interesting to play in but without the linear storyline from the original. Minimal Lore, starting character, Factions, locations, entities, skills, basic semi ok systems and settings.
