About Koi

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.

"Koi" is very nearly a hidden gem, with the only issues being that it's very easy and the graphics could use some work. You are a fish (A coy, I suppose) who collects other fish to open flowers, avoid enemies and complete simplistic puzzles. It's very easy but some of the achievements require a bit of work. There is a weird, strangely beautiful cutscene hidden in the game if you complete an upstream section really quickly, but some of the graphics are just hideous, especially at the pipe section of the game. The music is beautiful and it's not a bad way to spend a couple hours. I liked it but it needed a tad more effort on the presentation side to be truly wonderful.

I can only say that for the money you paid is worth it, but I can't really say anything else positive, a lot of times it feels like it desperately makes you lose as much time as possible to make you lose time (and not for atmosphere), the star level above all else feels just frustrating with the white fishes only getting in the way while not being a real threat, the immense and useless space made just for you to make more and more rounds. If the star level was instead some kind of playable credits it would have been way more fascinating. Because of these solutions the game quickly lose the atmosphere of its magic, aside from some highlights that make the title worth of its price

I was looking for a relaxing game, but ... I can't relax at all. You're constantly bombarded with sound effects of water drops (which I perceive as stressful), and there are no options to adjust the SFX or music volume. It's possible that other players find those SFX relaxing, so ymmv.
