So I think this game is pretty awesome, but Limited Edition is a horribly designed challenge. And it didn't get any better when you added shape shifter, which was even worse. I get a challenge sometimes requiring resets, but the amount of times I had to reset these challenges are obnoxious.

I only had to play Shape Shifter twice but I can see why Limited Edition may be hard for most players as I had difficulty with it as well. In any case, they're supposed to be hard so I can't understand why it's a bad thing.
