I'm having a lot of problems just getting through Tower of Goo level in the first chapter, nevermind getting the OCD (which I won't even try). Even watching videos on YouTube does not help. No matter how closely I attempt to follow what the videos do, the tower keeps falling over.
Does anyone have hints or walkthroughs on how to get through this level? Or, perhaps generic tips for World of Goo -- I might be missing something important?
