On Briliant Island many puzzles are related to the phenomenon of divergence, that splits characters and objects into several independent fragments.
While all the player character fragments are controlled by the player at the same time, each may interact with the world differently depending on their variance. Mastering this rule will prove useful to solve the island puzzles but could also become your main obstacle to the treasure.
The use of a new spectral rendering technique allows anyone to customize the look of the game in the settings.
At any moment you can apply a colored filter by pressing Q or E. Pressing again switches the filtered colors or deactivated the filter. It may help to understand the basics or if you are overwhelmed by too many colors on screen.
The φ (phi) Assist indicators allow you to see at a glance what components any subject is made of. You can toggle φ Assist on and off by pressing P and in the settings.
Controls can be remapped in the settings.
