My gosh that was intense. The fact that there are 18 endings astounds me and I am so glad you provided a walkthrough or else it would have been real confusing over what's happening. I love how out of the blue Sable suddenly appeared, there's no reason why he does this, he's just sick in the head. Not only that but I adore how he is the only pop of color in this VN yet he's by far bloodthirsty in a sick way. I love the first 4 survivable endings were just the revenge ending because frankly, no amount of trauma nor defending can make me say "Oh no the poor pastel pink baby--" like no, suffer.
But I also like how the last 3 survivable endings where Sable becomes enamored with us is the one where we nearly die after getting his "affection" up because I would have never anticipated that, sure hope MC is alright in those endings...
Yet I have to say, the 11 bad endings were cool but pretty difficult to keep track off since there are so many choices which is why I thank god you have the walkthrough. I can't say much about whatever was going on because it was a whirlwind of events but amazing job here!
