Worth buying to get the extra levels

Ive been playing a lot of these games lately and this one was pretty good. A few of the puzzles were so obscure that even after I got the answer from the walk-through I couldnt figure out how they got that answer. Also, there were a few items that would not let me pick them up the first time I tried, but seemed to rely on something else needing to happen first. I get that for manipulating a puzzle - all the pieces need to be in place first. But things that need to be picked up should be available if they are just sitting out there.
