Keep Them Warm is a 3D game with beautifully drawn, high-quality graphics. In this game, the player must control the Sun to make sure the species on Earth doesn't get freeze to extinction. The Earth will continue to rotate forever and the player must angle the sun to make sure that the sunlight hit every corner of the planet for as long as possible.

The Earth will start to lose heat if a lot of areas didn't get enough sunlight. If the Earth's heat dropped below 50%, some of the life forms will die. The player can still save the planet if they can raise the temperature fast enough. But they have to be careful since raising the temperature too high will cause forest fire and desert to form.

The Earth's environment will be procedurally generated throughout the game. The player can navigate to any part of the world that they want to check out. They can also take a beautiful screenshot of their sun lighting effects.
