Mission Mermaiden: Hasumi and the Deep Sea Sist is not a perfect game. The inventory system can be clunky to navigate while bobbing in the water, and some of the late-game backtracking feels like artificial padding.
However, these are minor grievances in what is otherwise a monumental achievement in atmospheric storytelling and unique gameplay design. It dares to be different. It takes the player out of their comfort zone and forces them to adapt to a new set of physics and rules.
For those looking for an experience that combines the tension of a survival horror game with the traversal joy of a platformer and the heart of a buddy-cop drama, this is a must-play. It is a haunting, beautiful ode to the parts of our world we have yet to fully explore.
Final Score: 9/10
