This game used to be great. – Color Zen Review

I remember having bought this game a while back, when it was a straight up purchase (not in-game), and playing through much of it; I'm talking chapters, not just levels. Now I can't access the full original game anymore. On top of that, it's glitchy. For shame. Update: Did the thing to restore my purchase of the classic game, and chapter 2 remained locked with a dollar sign... until I got to it. Then it suddenly unlocked. I'm thinking that maybe the purchase interface is not quite communicating to the level select that a purchase was successful, despite the cart claiming as such. Bumped up from 3 to 4 stars. Still a tad glitchy, but appears to work.
