Gameplay of ASCII RPG with aborigins who going through the jungle following a river

I develop the game with a complex rules, where the player move with the tribe of aborigins trying to survive. One move is one year, so you have to make new generations for overlive more then one live cycle. There are many dangers in the environment the tribe live in, including strange desieses, mosquitos, halucinogenic plants, predators and so on. Game is early alpha version
