I (and my houseguests) struggled with the Fisty’s Bog level of World of Goo a lot over the past couple of days, but I finally got it today. One thing that really helped me was building up as my first move, instead of out, as well as learning that I could put the balloons on any goo ball, not just ones on the top.
My TV isn’t quite wide enough to show both ends, but on the left, the frog is just barely cut off, and on the right, the pipe is close enough to the last point of the last triangle that it was able to get all the goo balls.
how is your TV not wide enough!? your TV is monster!
