This game uses XNA was is written in C# and was made during my second year at university
The game presents the player with a screen of hexagons representing radioactive cores in a reactor. By clicking on the cores the player turns on the core and it generates heat and the hotter it is the more power is produced. The player has a task to generate power for and needs to sustain the power for long enough for the bar to fill. If the core gets too hot it will begin to take damage and will eventually break and stop working. To generate more power you need to cluster the cores you turned on as the cores spread heat between them. By pressing space or enter you can turn all of the cores off or on and by pressing z and x you can turn on cooling and shielding. Cooling reduces the the temperature throughout the reactor. The shield prevents the cores from taking damage.
