I uploaded the wrong file, I changed the encryption key and forgor. Shit my pants when I realized my mistake only to come back and find the file had been downloaded already, the link should have a working file in it now, but glad you got it working :) Your old saves should work btw, you can just move the save folder over.
(The cave scene you mentioned is supposed to game over, if that's what you meant by dead-end that's intended.)
