Breinrot Bog

Welcome to a world where the mind is devoured by a mysterious substance — Brainroot. This substance appears in the most dangerous and inaccessible places on the map. Your main goal is to collect it to survive and strengthen your character. The main threat is the awakening swamp. The water level is constantly rising, flooding the land. If the swamp catches up with you, the character will die, but will immediately be reborn at his base. However, death is not the end, but part of the strategy. Return to flooded areas for new resources and watch as familiar trails become impassable. Spend the collected Brainrots on leveling shelters and improving stats: increase your movement speed to escape from the water, boost your jump power to jump on high ground to escape the flood, or invest points in income to passively receive resources even in idle time.
