Note : I played this game on two android devices, they are not synchronized.
On the first device I managed to come to the skeleton and chest, then managed to climb down the rope ladder at the waterfall.
On the second device I wandered on another path and arrived at a temple, and fiddled around with the statue, which dragged me down into a watery grave. (Adventure writers sure are a sadistic lot, but I digress). Anyway, managed to figure out that I need to DROP STATUE and go down, then north. There I find some boots which I can wear.
However, this part is a dead end. You can't go ahead (as you need the rope ladder to climb out) and you can't go back through the well.
Quite interesting. Unless I'm missing something?
