A lot of strange anomalies in GooUniverse have caused the creation of new puzzles that are so insane they could mess up your mind and turn your brain into ooze! New traps, new buttons, new aspects to the game
These games are currently $0.49 each. To get them free requires three steps, and I can only see that the first one is to join the group on Steam. Is it worth doing the three steps to get them for free?
If they were related to World of Goo I'd do it in a second but seems like these Goo games aren't related…
