This is very much my cup of tea, hehe. I'm an absolute sucker for bad endings and bleak atmospheres, and boy did this deliver on both counts!
I managed to get all of the endings :3 It did take me a little while to figure out how to access the ability to save (I eventually found it with my mouse wheel click rather than escape cos I didn't read your comment reply here until just now >.< I found skip first on the S key, and then just pressed everything else until the menu popped up :3) But yeah, once I got that figured out, I was off exploring all the options :D
I don't want to say any sort of spoilers, but I will say that I think my favourite endings wound up being the one with the same title as the game and maybe tied with the Stalking Corpse one. Sorry if I'm getting the name wrong there >.< That was the first one I got, and I didn't think to make notes.
Anyways, I love it :3 The art is gorgeous, the dark story is very much the sorta thing I'm into, and it's going straight on my recommendations list on here <3
