How mysterious is that? ;-) Thanks for playing!
The first level is black, and you can do nothing (except hit the escape key or wait).
Then each level is a color of the Rainbow: Red, Orange, Yellow, Green, Blue, Indigo, Violet
Built from Sevens and CompAltars. You are looking for the Gateway to the next Color
Which is another RainbowHapt(agon), but with one more Color inside of it...
How far did you get?
