You got through the game! :D Thanks again for the wonderful series of vids! As for the endings, there isn't really a "bad ending" unless you count the various deaths throughout the game. There is a default ending, and then there's a track that will lead to two other possible endings that reveal more of the story if you discover all the clues, so that was just the default ending. That's good feedback about perhaps adding something before or after the credits! I'll look into maybe doing that...
If you want to try to get one of the other endings, I could give you some advice, if you'd like, but if not, no worries! Thanks for playing!
