i have a far more fleshed out idea in terms of lore and shit but this is the base concept

game idea im working on: an underwater survival game somewhat similar to subnautica with more of an emphasis on combat. most importantly, the local fauna respond to the player's presence, and take action regarding your own actions. the smallest of creatures my approach you at first, pondering a possible source of food. yet all but the most gargantuan of creatures will flee from the player when they cement themselves at the top of the food chain.
