Landing on a sloped surface will be an issue. Apollo 15 was close to disaster on its tilted landing and Apollo 12 had a bobble when setting down. Starship is unlikely to survive the same.
Starship will have spare fuel and relightable engines. It could just take off when it starts tipping and go for a second landing attempt on a more even surface. The low gravity is a real pain for landing, but it makes it really easy to abort a landing too, even after touch down.
Except they have no depth of experience doing a non-hoverslam landing (0 on dirt) and there is a serious risk of damage from flying debris. Apollo only had 2s max to perform an abort on a known good engine. Expecting a restart to work reliably with minimal delay is ambitious.

... A surprisingly kerbal solution. Wouldn't the engines be firing to control the vertical speed though? Otherwise it'll end up lithobraking at hundreds of meters per second instead of gently touching down at 1 or 2 m/s. At least that's what happens to me if I don't burn retrograde.
