Ohh thank you for playing!! Yes, I hoped it wasn't too scary so that most people could enjoy it (I'm a bit of a scaredy-cat myself, haha!) I'm really glad you enjoyed it :)
Ahh I think that you missed Ending B! For this one you need to be as cruel to Raku as possible - the key choices are to tell him "You're suffocating" and "Be cruel" (while also being as neutral as possible on the other choices - don't give that man any hope, haha!)
