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.
Features:Just the tutorial levels. Beat the clock. Earn more time by working quickly. Get light to the Glowbos before they explode. Increasingly tough levels to complete at your leisure. Random levels. No time limits. Just keep playing.
Gameplay: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.
