Wow, thanks for even spending time on the game! The game is based on morality (think demon vs angel and all that devil on your shoulder type stuff). So you pick the "right" choices/doors, and you'll be reward with two endings. The End, and something around the end...
Thanks for the love!! Thanks for the comment on the bug, I've noted it as well as the sound settings. YOU ROCK!! and YOU are the cool one!
