i played this game with my sister, and it was a very fun and brain-teasing experience to try and find all of the endings. we felt this kind of tense pressure, and there were no smiles and laughs due to the tension--WE HAD TO SAVE TIM!!
we both loved all endings though. definitely unexpected every time and we didn't know whether to be happy we unlocked a new ending or sad because of what it entailed! lol
