Evaluation

Panthalassa is a point-and-click adventure game developed by Meia Calça that launched on May 17, 2026. The developer has remained actively engaged since release. On June 17, 2026 — one month after launch — the developer posted a celebratory update noting the game's positive reception and teasing ongoing community activity around an ARG. On July 16, 2026, the developer shipped an update adding a full Portuguese translation, fixing several bugs, correcting text in an ending, and hinting at a hidden secret addition. In that same post, the developer stated they hope to continue translating the game into more languages, specifically naming Japanese and Simplified Chinese as targets for later in 2026. This indicates the developer is actively working on the game beyond its initial release and has communicated concrete plans for further additions. There is no indication that development has concluded.

About this game

PANTHALASSA

In Panthalassa, you delve into an alien underwater world where you play as Magellan (aka MAG), an autonomous exploratory submarine who suffers a catastrophic malfunction and awakes anew, reborn in a highly advanced body, in a world they do not recognize. With technology alien to them and new emotions that were not there before.

In this game, you must find out where you are, whose body you inhabit, and if there are any hopes of returning home? There'll be secrets to uncover behind an mysterious civilization and your body's previous inhabitant - you may even find out a bit more than you bargained for.

Panthalassa is inspired by Point adventure games from the 90s and early 2000s. You see the world through the eyes of a machine and must navigate strange user interfaces where the digital and physical worlds clash. You will find new Aquatic Specimens, catalog them, solve puzzles and organically discover hidden information by searching every nook and cranny of this bizarre digital world.
