- Genzo’s stall and Aya’s forge set different prices for each fish species, making where you sell part of the game loop.
Field notes
The page documents a loop that moves between Koi Lake, Koi Landing, and the Crimson Thicket: catch fish, sell or cook them, reforge a blade, then take on harder fights. It names the control schemes—J/K/L/Space on keyboard and four buttons plus a stick on phone—and explains enemy tells such as the Kitsune Hunter’s straight-line lunge. The site says saves remain in the browser; co-op rooms are described as code-based, with a room server synchronizing fights.
