Refraction is a physics-based game where you control a set of lasers, each of them has a different color and power, and you have to combine them in different ways to solve the level. It is based on the same concept as the classic beam-splitter, but with a twist. You have to combine the colors to make the laser beam split into different colors, while the power of each laser is controlled by the environment in which you are playing.
The gameplay is very intuitive, and all you have to do is tap the screen to set the power and the color of the laser, then tap the screen to start the level. At the beginning of each level, you will be given a hint of the solution.
