I have enjoyed playing Mirror Magic. Unfortunately, I cannot access the Heavy Mix when playing. After beating the regular level, then the next hardest, the heavy mix icon is still dimmed. I purchased Mirror Magic from Amazon. It is fun, and really makes you look carefully for the tiny differences. The mirror image series is by far the most difficult. I like that when you replay, it has different "differences" for you to find. This game would be great for 10 and ups.
