If I paid money for this thing I'd be furious with how short it is. My first go around the novelty lasted about 4 minutes before I just got frustrated and annoyed. I powered through begrudgingly, pretty much hating it all the way to the end.

The post game content (optional challenges and level speed runs) is where I actually found myself enjoying it some. Less banging your head against a wall figuring out what the game wants from you, more knowing what you have to do and devising a plan for how you're going to go about it.
