tuna hake's underwater

Tuna Hake's Underwater launched on April 24, 2025. Since release, the developer (a solo indie dev, osuika) has been actively updating the game. A major content update on June 1, 2025 added a new Swamp level, seven new fish, and a first-person mode. Prior to that, a substantial feature patch on May 3, 2025 introduced free swim mode, keyboard controls, a tutorial level, and additional fish, followed by further quality-of-life improvements on May 11, 2025. The most recent communication was a bug fix patch on July 5, 2025. The developer has not announced any future content, nor have they stated the game is complete. The store description describes this as a short, toy-like experience, which is consistent with a small-scope indie title — but the post-launch update history shows the developer has continued adding content beyond what launched. No specific future content has been announced, but the developer has maintained an active update cadence since launch with no indication they consider the game finished.
