Panthalassa asks a simple question. What would it feel like to float on an endless ocean that existed before the continents split, where time moved slow and the only sounds were the rush of deep currents and the calls of creatures that no longer exist. This 2026 adventure casual indie game from Meia Calça answers with a sensory meditation. You take the role of a drifting observer, moving with the flow of a vast, alien sea. There are no markers, no objectives, just you and the water. The game encourages you to stop steering and simply be carried. Occasionally, you might notice a faint light in the distance or a shadow beneath you, leading to a hidden lagoon or the song of a lonely whale ancestor.
