ColorFold 2 by Martin Pluisch $.99

ColorFold 2 comes from Martin Pluisch. Last year he published the first version ColorFold.  I really liked it. 

 There are 150 levels.  They are much much harder than the original game.  I only solved 47 levels.

All the levels are split into 9 Acts.  So I got to sample the various elements.
