Whoops! Apologies to all users who have downloaded the supposed V1.70 or a version with no edge setection in the cave level, since the website update, its not! because im hosted on Linux, I recreated the file with .zip in capitals, and of course it thinks its a different file!
I have since given myself a smack in the mouth and it has now been fixed & ready to go.
