I know a lot of other people have said it but damn, I'm impressed with the way you animated those cutscenes. I never thought you'd be able to do convincing POV 3D in Flash!
I figured out the save thing. You have to start a game, finish the tutorial and then quit from the pause menu (press Space in the game). Once you do that, the main menu should give you the "2 Player" option and going back into "1 Player" will give you the Story option where you can select a chapter. It's not a save in the strict sense of the word, but it still beats trying to clock the game in one sitting!
It'd be 5/5 if the Save function worked. For some reason whenever I come back to the game it doesn't give me the option of continuing. A brilliant game in all other respects - one of my faves.
