I restarted the game, now with a walkthrough to check step by step what i might have missed. And encountered 2 hideous elements.
1. The "Jump back to the double sloped ledge then line up for a long run and jump to the high sloped pillar to the West, (left of the alcove you entered here by)" is impossible unless some bug should be used to advantage, but i haven't found it,
2. The jump to catch the hang-lever on the brown pillar depends on the bug that when Lara cannot reach a lever, she is suddenly pushed upwards and magnetically attaches herself to it.

Anyway, i can proceed now. Missing one golden rose but so what, knowing now this level isn't that great after all.
Also in a next section small sloped pillar jumping near impossible jumps so you keep trying dozens of times to find the only working exact right angle... making each step impossible until you have found out after numerous trial and errors. The preference of the author for the neurotic is remarkable. But a talent for making a good game: in this early creation, no.
I stop here, it's just a waste of time, no pleasure at all.
I rate Eastern Sanctuary 4 / 10
