Invisum Piscium 嫌魚, a new walking simulator, invites players into a surreal and dreamlike world centered on abstract exploration and a peculiar obsession with purified water. The game's premise revolves around a deep craving for water that has not been contaminated by the act of fish procreation.
The game's Steam page emphasizes its focus on atmosphere and exploration, noting the absence of traditional puzzle elements. Players can interact with objects to subtly alter their environment. The demo opens in a bathroom, where an interactive rubber duck provides an early example of the game's unconventional dialogue and interactions.
From the bathroom, players enter the main apartment area, where a character resembling a plush doll come to life explains her anxiety about drinking water due to fish mating habits, initiating a quest for distilled water. The demo's progression mirrors a small-scale trading sequence, involving exchanges of various items to achieve objectives. For instance, a goth character with a cat plush offers cake due to feeling empty. This cake is then given to a bunny girl, who subsequently explodes and dies, only to be revived with an energy drink. The cycle of item exchange continues with found money being used to buy a snack for the goth character.
Cryptic messages are delivered by floating ghosts throughout the apartment complex. Players can observe the skybox, with visible clouds and the edges of the world, prompting contemplation about the game's boundaries. The demo for Invisum Piscium 嫌魚 is brief, and the potential scope of the full game remains unclear. It draws comparisons to indie classics such as Yume Nikki and more recent titles like nophenia, suggesting a shared focus on immersive, dreamlike exploration.
