Minor observation, the cliffs don't look steep enough to me, IRL they are near vertical. In fact at the base of the cliffs they are undermined by the waves.
Sorry to nitpick but I live on the South coast & see 'em nearly every day!
Unfortunately they can't make them any more vertical Gnasher. From my understanding it has something to do with the game limitations. It is a compromise they are stuck with at this time.
If I am wrong I am sure Booze will be along to correct me or explain it better to you.
