Evaluation
Koi is a compact, self-contained adventure game that launched on February 22, 2019, with eight stages. The store description presents it as a complete experience with no mention of additional content, expansions, or ongoing development. The developer's news activity on this game's page has been minimal and winding down: a bug fix in July 2022 addressed a star-collecting issue in Level 8, and all subsequent posts have been announcements of the developer's other games (Breaking Box: Rush! in October 2023, and BackSlap in June 2025) with Koi only mentioned in passing as part of a promotional discount. None of these posts indicate any new content, updates, or future plans for Koi itself. There are no unreleased DLC listings and no developer statements suggesting further content is coming. The game appears to have shipped as a finished product and received only minor maintenance before the developer moved on to other projects.

About this game
Introducing KOI
KOI reflects a tranquil and mesmerizing experience as you embark on an introspective journey through the lens of a lone koi fish separated from its owner and is the last hope for purifying waters polluted by mankind. It’s up to you to turn the tide and guide the koi through eight artfully rendered stages that will take you into the murky as well as enchanting waters, deep below the surface.
Turmoil and Serenity on the Horizon
Become immersed in the life of the lotus pond with a spellbinding soundtrack as you guide the koi through unknown waters. Cleanse the tainted waters by maneuvering past obstacles, solving puzzles by guiding koi to open flowers and release the Light Fish, memorizing melodies hidden within deadened branches and restore the ecosystem.
Explore the Ever-Evolving Koi Pond
In the award-winning game, KOI the lotus pond takes on a life of its own as it is presented in vibrant, high definition visuals optimized for PC. The world is waiting to be uncovered and you must help restore the ecosystem along the way.
Peace of Mind
Escape the realities of life and achieve a level of mindful satisfaction.
