Well, that wraps up the game, you'll get a nice little happy ending cutscene plus hints at a....sequel? We can only hope. There's also no more you can do in this game unless you go back to before "the point of no return" at which the game will auto save for you in case you didn't. If you then go back there and complete anything I missed here then to really take advantage of it you would have to complete the rest of the game again (the meat circus).
Well, I hope you enjoyed it, sorry I didn't get EVERYTHING, but I did what I could with one play through, feel free to go back again and send me anything I missed, or simply enjoy the beautiful levels of this game. Thanks for checking out my guide! Rock.
