This was really fun! Sable is adorable, and I love the range of expressions + hints of his personality that we get through dying by his hands or vice versa. I haven't gotten all the endings yet, but the last of the survival endings has to be a favourite- I was hoping there'd be a bit of a "happy" ending in there. Also just to note, when informing Sable of the MC's name, they would say "Oh, MC!" even if a name had been set.
Is there any chance you might consider releasing an ending guide, out of curiosity?
