The survival of the Nimbies is under threat! The atmosphere of their planet Nimbylon is on the brink of collapse and the only hope lies with the brilliant scientist Nova, who has discovered the key to solving the Nimbies' problems.

Unfortunately, Nova has been kidnapped by a group of evil Nimbies who are determined to keep things on Nimbylon the way they are, whatever the cost!

As Healthy, the loyal best friend and sibling of Nova, you must bravely step up and journey across diverse planets to unlock secret powers and solve unique (renewable and non-renewable) energy puzzles to undo the damage done by the evil Nimbies and bring Nova home! But be careful, because the atmosphere's deterioration threatens not only your own well-being but also the lives of the inhabitants of each planet.

Travel the universe and help alien races along the way!

In your quest to rescue Nova, you will travel to different planets and meet other alien races in need of help. Solve puzzles to help provide power for aliens including the Galetonians and the Solarians, and restore their environments in return for clues.

Change the atmosphere!

Healthy’s actions all have an impact on the atmosphere. Make sure to consider this when solving puzzles. You can check how well you’re doing by visiting the control panel of your spaceship.

Learn new skills (and powers!)
Each new planet and its inhabitants will provide Healthy with new skills such as harnessing more sustainable energies to improve the atmosphere. Nova always said that Healthy was a powerful friend, but we will discover that there may have been more to this than meets the eye! Perhaps the key to the Nimbies problem was inside Healthy all along?

Save Nimbylon!
As you learn new skills and acquire new powers, return to Nimbylon to make changes, restore the environment and save the Nimbies!
