Okay. That dang platform puzzle was what was holding me back ... and putting me on the verge of giving up as well. The simple unforgiving nature of it is a real pain - it took me a while to work out that the platforms went too high to walk on at the top and that was why they went back down if you got on them - and sent you down into the lava, with no way out and a lot of battling to repeat, yet again (frustrating even on kindergarten - it doesn't make the puzzles any easier).
But after sorting out those platforms, the simplicity of the rest of the level was a bit disappointing really. I liked it how it came back to the same pattern buffer from a new aspect, but then it wasn't entirely clear that returning to the start would get us out of the place. Never mind.
