Escape in 120 seconds:
Run to the illuminated areas and try to climb the ropes.
Right click on the ropes first to check if they're climbable. Using the wrong rope will result in you taking damage.
Use freedom and anticipate where possible.
The falling rocks can kill you (which will be an unsafe death), but running out of time will only result in the escape sequence being reset. If either happens, the minimap will be usable in the next escape attempt.
