About the Game
Loddlenaut is an ocean cleanup adventure set on a vibrant alien planet. Play as an interstellar custodian who is tasked with cleaning up the pollution left behind by a spacefaring mega-corporation. Befriend local axolotl-like creatures and explore sunken corporate ruins as you revive the planet’s lush ecosystems.
🚀 Explore an open-world alien planet
🐠 Raise aquatic critters called “loddles” that grow based on what they eat
🔫 Clean up icky goop and floating debris with your bubble gun
🌟 Unlock special gadgets to clean different types of ocean pollution
🛠️ Recycle collected trash to craft useful items and upgrades
BRING GUP-14 BACK TO LIFE
Your mission: Clean up the ocean planet of GUP-14 after it was abandoned by GUPPI, a mega-corporation that makes and sells everything from soda to spaceships. When you first arrive on the planet, you’ll find yourself amid murky waters, oil spills, and scattered junk.
Within the polluted environments, you’ll find remnants of GUPPI’s buildings, ships, and machinery all sunken to the ocean floor. Discover clues about the planet’s past inhabitants as you clean up the mess they left behind using an assortment of high-tech gadgets.
BEFRIEND ALL THE LODDLES
As you clean up the planet, you’ll run into axolotl-like aliens known as “loddles.” Protect them from the polluted waters and feed them aquatic fruits while you make their planet habitable again. Depending on their diet, loddles will grow in different ways and develop unique traits and abilities that will further enable them to survive on this polluted planet.
When the loddles are strong enough and the waters are cleaner, release them back into the wild and watch them thrive!
Goddles Update
Explore an expanded planet with three new caves that each contain a lost loddle with a new rare cosmetic mutation! Delve even deeper to discover Goddle Grotto, a secret sixth biome that is home to three mythical Goddles. Make use of the new gardening system to collect seedlings, grow your own flora, and increase each biome's resistance to pollution. Plus, track the positions of all pollutants with the new Global Pollution Tracker, expand your backpack with the new Inventory Capacity Module, and acquire gold versions of your tools by completing different milestones that will ultimately unlock a modified ending cutscene.
Loddlepedia Update
Track your loddle evolutions and see which ones you’ve yet to discover. Plus enjoy a new loddle ability, new loddle personality traits, new biome diversity ratings, and a new way to boost around the ocean!

1.2.4 Patch Notes - No more missing loddles!
Hey everyone! We’ve got a tiny patch going live today that fixes two bugs recently identified by the community. Fixes: Fixed an issue that was causing loddles to slowly swim back to the Home Cove (and possibly go under the map) when attempting to drop them off at a new biome after fast traveling. Fixed an issue that allowed the storage menu to be openable (and invisible) during the ending sequence. - Loddlenaut TeamRead full article on Community Announcements (LoddleDev)
