Hey mate.
Getting wrecked is no shame at all.
I got absolutely wrecked by the bandits in the ruis too. Then I reloaded, discovered what use an oil keg can be, and won the fight.
Same with the Goblin camp, or the (second) attack on the Grove (which was far easier after moving some objects)
It's incredible how much easier a fight turns out if you contemplate for half a minute and the restart.
On the other side I decided to not reload, after one of the characters got killed in camp, because opposite to losing a fight, It was my decision to watch the outcome - which was worse.
PS: I am doing it the other way than you did. I started in August alone in balanced mode, and are halfway through act2 by now. And started a co-op playthorugh together with my wife in easy mode two weeks ago.
So it will be a purchase on their website.
I was a day one buyer of World of Goo back in... 2009?
And of course I want to play the sequel too. Glad I don't have to use Some horrible web store, although I had preferred to have a choice where to buy.
