What do you mean for #2? How do you get drained (or was that a typo)?all three are proper Game Overs. There's two different ones where you become a pet/reindeer, and a toy end.
EDIT:
1: ask for feet at the shoe game (option 2) 3 times.
2: be fully drained (no equipment too) and talk to 2nd screen Claus while collared.
3: Open the third big box after the chimny
I suggest entering the chimney when this is showing in the room on the left:
To get through this route, you just need to go Down, Right, Down, Left, Down, then finally Left (changing directions when you hit a wall).
You need to use the heels to get through to the third box, but they should help at any time.
Depending on how you define a "good" ending, I don't think there is one. There is at least one "Happy End" where Ethan is enslaved, and a "Bad End", but all the ends I've seen are Game Overs.How to get a "good ending"? I unlocked all animations and buyed the shoes. I just can't figured out the meaning of stars in frame.
