Critical Failure Detected!

You are a commissioned nuclear engineer working on the night shift at your local nuclear reactor when disaster strikes. The cooling systems have failed and a reactor meltdown is imminent. As the only engineer on site, it is up to you to save the facility from a nuclear meltdown!

What Is Meltdown?

Meltdown is an isometric puzzle game with the goal of repairing coolant pipes that flow through the nuclear power plant. In this game, there are a variety of mechanics the player will need to familiarize themselves with in order to complete the puzzles. Some of these elements include power sources such as Switches, Buttons, and Crates, which in turn activate equipment such as Access Doors, Bridges, and more! All these mechanics are driven by a color-coded power system that the player will use to find an effective path of fixing these pesky pipes. With all these concepts in mind, the player will dive deep into the chambers of their local reactor to repair their cooling issues and save the day.

Each level awards you with a star rating based on run duration, can you find the most effective way to reach the pipes?
