Updates have ruined once-perfect game – Color Zen Review

Color Zen used to be my all-time favorite game. The last couple of updates, however, have ruined it. Shapes collide when you don't even touch them (Classic, Chapter 4, Level 20); some levels are literally unwinnable (Nature, Chapter 1, Level 16). I don't know why the developers felt the need to fiddle with this once-perfect app, but they've ruined it, and they don't seem interested in fixing it. Very disappointing.
