Ah, never mind. I eventually cheated my way out of that corner. I'm not exactly proud of that, but I wanted to see the rest of the level... :-(
Overall, btw, I really like the look of this level. I think I've said this before, but I especially appreciate your use of colour. The only point of aesthetic criticism I have is that the temple area is too... hugely pixelated(?) to fit the rest of the level, and especially the areas directly adjacent, and the other tileset you're using in the temple proper. But apart from that, this really is a very nicely designed level.
(I'm still not done with the level, so this is just a bit of intermediate feedback.)
