This game may require some level of skill or puzzle solving skills. If you cannot pass a level, feel free to skip it using the editor. However, there is a very small chance this will break the collectibles, but it probably won't. Or you can just read the guide here.
The game may also be a bit laggy if you are on a lower end computer.
Illuminant, the physical form of light, has stolen all light for it's own. You must defeat it using the other 4 elements, Water, Fire, Earth, and Air.
