The awesome, alien visuals in every section go a long way to keep Project MANDELBROT fresh even when the layout slumps a bit in some parts, but I still can't help but feel like there was supposed to be a more coherent sense of progression through the level. I don't know too much about the Mandelbrot set, but I do know that it's been mapped extensively enough that there are catalogued landmarks pretty far in - I'm assuming that subsequent parts are chronological as you zoom in to the set, but while the song swells and contracts, every part feels basically the same in terms of intensity and how peculiar the patterns get; you could probably arrange them in (almost) any order you want and the experience would be basically unchanged.
