In Prism, the player, along with a number of Bulboids, must direct light onto the Glowbos, making use where necessary of the galactic matter, which comes in the form of Mirrors, T-splitters, Filter Blocks, Spinners and Prisms, collectively called Gluons.
Bulboids: These friendly creatures from outer space light the way with their powerful beams. Place them carefully to help the Glowbos survive.
Glowbos: The peaceful Glowbos need light to survive and use it as their food. Make sure they are lit up by utilising the Bulboids.
Mirrors: These reflect the light at right angles.
T-Junctions: T-Junctions are very useful as they split the light into two beams and so give the player more options.
Filter Blocks: These change the light beam to whatever colour the block is and as such are very useful to light up the coloured Glowbos.
Prisms: They split the light into three different beams of red, blue and yellow allowing the player to solve even the toughest of puzzles.
Cycloids: These creatures behave like filter blocks but they cycle through different colours. Make sure you pay attention to the direction they are facing.
