I had a lot of difficulty watching that through streamlining. Its pretty boring that one, an expo on the levels wasn't really needed. I know their trying to sell the game before its released, but they are trying too hard I think.
I've got mixed opinons of the backgrounds so far. some of them are good, but others are not so. I think the puzzles are going to be the most annoying thing about the game. I only hope they don't take the fun out of the game, like some of these types of games do.
