Getting back into the game

Defeating the laughing octopus this time round was significantly easier, simply due to knowing all the patterns already. I do like the leaking the color out of the scene effect that is used at certain sections. Very artsy and very well done.
Then I played for at least an hour after that and remembered to save.
Why can't these folks auto-save upon zone transitions (like half-life 2). I was saving every time I could simply to be on the safe side.
