There is only one ending to the game ^^'
lol I see now that they were being sarcastic... I was assuming from the way things were worded in the description (good behavior will be rewarded, everything is a puzzle, true story is hidden in plain sight, etc.) that there'd be a good ending for making certain decisions or performing certain actions. My suspicions were raised even more when I found that some of the windows upstairs could be boarded up. Couple that with the reference to a weapon being hidden somewhere and I think you'll see how someone might get the idea that there's a better outcome waiting to be unlocked. Bummer!
