The lunar lander was lightweight and relatively fragile, designed for low gravity and low pressure differential. For example the aluminum alloy skin seems vulnerable to distortion and to sharp impacts, because it was 0.3mm, about 3-4x thickness of a modern soda can, though the frame supporting it was much stronger. I thought the safe take off angle was very limited, but some NASA research says that even up to 70 degrees tilt could be manageable if the crew handled it correctly. https://forum.nasaspaceflight.com/index.php?topic=32246.msg1068329#msg1068329 https://forum.nasaspaceflight.com/index.php?topic=32246.msg1... That doesn't mean 70 degrees would be safe for landing, though. Maybe it would topple or get damaged by rocket blowback. Apollo 15 was tilted about 10 degrees and that was not a problem.
