About the Game

From the creator of reactor idle, factory idle and city idle!

Your mission is simple: HEAT UP THE PLANET, Yes, really.

You’ll start with clean technologies like solar panels that barely produce any heat, but soon begin to research less clean methods to produce even more heat. Who knows—you might
actually succeed in overheating the planet.

Managing excessive heat, however, is not an easy task. Be prepared for challenges and, yes, explosions. MANY EXPLOSIONS. In your defense, explosions also help heat up the planet. Explosions cause financial losses and can bankrupt you though...

This game introduces new features gradually. At first, you’ll see only the basics to help you get started, but as you progress, more advanced technologies and mechanics will
unlock. It is a long journey with plenty to explore.

Disclaimer: This game is HARD.
It is also a form of a puzzle game, requiring you to figure out efficient strategies to improve your setup and boost your income.
Keep in mind that perfection isn’t the goal—you’ll need to focus on specific areas and make trade-offs.

Are you ready for the challenge?
