The title is a tribute to video game composer and musician Richard Joseph.
Using the light emitted from the Bulboids, alongside a set of items collectively called Gluons, the task consists of guiding the beams to various Globos scattered around an area. Furthermore, Bulboids only emit white light, thus providing a need for the use of prisms to split the light into separate colors for each specifically colored Globos.
Accompanying the Bulboids and Globos are the Gluons, a set of items that can be used to redirect or break light into set colors.
- Mirrors: These can be used to reflect the light in a 90 degree angle across the stage. Both sides are usable.
- Filter Blocks: Filter the color into the color of the block itself.
- Prisms: Prisms split pure light into different colors to be fed to hungry Globos.
- T-Splitters: Split the light into two directions. They cannot be rotated.
- Cycloids: Cycloids filter light in the same way as Filter Blocks, but will rotate through an assortment of differing colors.
In addition to the main single-player Puzzle mode, a handful of other modes are available. The aforementioned Puzzle mode contains 120 puzzles of increasing difficulty, logging the best times of each individual puzzles on a scoreboard. Tutorial teaches the basics of the game, while Time asks players to complete random puzzles before the Globos explode. Infinite is an endless stream of puzzles and lastly Hyper tasks the player to light up randomly placed Globos in a single square room.
Local wireless multi-player modes consist of Co-op, a mode where both players control a single screen and must manipulate objects to reach the Globos on both sides while the other half of the action is invisible, and a competitive game to determine which player can solve certain pre-set puzzles the fastest. All multi-player requires 1 game card.
An in-game achievement system also keeps track of the more notable missions the player has undertaken.
