Very funny! I really enjoyed it, here are my only suggestions.
Need to work on using <NOD and <CLR when adding text. Make sure to use <CLR when you change portraits with <FAC, that way it dosn't look the new person is saying what the person before just said. The chat with Cthulhu in his abode might need to be changed if you are changing story behind the main character.
I suggest, you make it so you can save whereever you want. So that when you test diolog in game easier. Really thats the only problem I have seen. In armsitems, change event #7002 to read <SVP<END. This will let you save wherever you want. Making it easy to look over text events, and make sure everything is just right.
Is there any reason to break into santa's house? I think you could break in from the door intead of the skull also. Once you break in tho, you should be able to go back and forth w/o having to break in and get the "just got something" music to play every time.
