So, I played the game for like an hour last night, and I don't have any save data. . .I looked explicitly for a "save" button, but could not find one. . . .
Am I missing the reason for a "continue" button, or am I missing the "save" button?
The cave isn't "endless." Your wolf mother abandoned you in a cave at birth, and you fell until you were 13. While falling you found out how to throw rocks to make you fall slower, as you can see by the fact that you lived. After living at the bottom for three years by eating the bodies of dead enemies and dirt salad waiting for your inner ear to finish developing, you begin your long quest out of the cave.
