Aargon
Description
Aargon presents the player with 120 grid-based levels of light-refracting deviousness.
Each level has a set number of light emitters, that emit 'laser' light in a straight line. Also on the level are various 'coins' of differing colours, which the player must pass the correct colour light into to set them spinning. Once all coins are spinning, the level is complete. Each level also has a set number of objects that you may rotate and place wherever you want. These objects include mirrors (that reflect light by 90 degrees), prisms (that can be used to split a beam of white light into three beams of red, blue and green), splitters (that take a beam of light and split it into two identical beams), as well as many more (including polarisers, refractors, filters, etc.).
Whilst the initial basis of the game is very simple, some of the more complex levels can take hours to solve.
