Tim Schafer made available his original puzzle design document for the game on the Double Fine site, commemorating ten years of its original release. The PDF file can be downloaded here, and obviously contains spoilers and other details about the puzzles, including ones that were cut from the final game.

Interesting. Even more so, I imagine, if you've played through the game, like me.

Wow, I didn't even realize, one of my favourites had 10th anniversary. Thanks for posting the link, but I'm apparently too late, as the document seems to have been removed from the page (maybe due to trouble with LucasArts?)

Anyway, I think I'll celebrate the anniversary by giving Grim another playthrough as soon as I have the time.

You can still get it from Kotaku.
