34 is tricky because you think about tilting the two pillars from the center block. This is not the correct way to do it. Tilt one pillar over the center block to make a floor, and then put the other pillar over the center block. Use the two smaller pillars to make a wall on both sides and then start stacking the circles
I liked this game and I would love to see a new and improved sequel or update, but there were a few drawbacks I'll like to point out in the most constructive way possible: After having the workers cross the bridge, some of them actually get stuck pushing the crates on the default level geometry. It's frustrating when I build a perfectly sound bridge and the guy can't push a crate up the grass. Also, the instructions in the beginning need to be a little more clear. I was way confused until I watched a youtube video do the second level. Yeah, I know I'm retarded but I wasn't really clear on joints only locking in with other joints. That is all. An overall great, and fun game though.
