Amazing game although I do have though I do have to say after playing the game through if i hadn't read the comments sections I would have had no idea this is a multi-ending demo or even game. I found myself constantly failing on purpose to explore scenes and choices.
Looking at area's like the door that can not be unlocked with a key that was not unlocked by doing a hitless run Nore by having no corruption. I was left lost assuming this had not been implemented or that I had reached a Bug.
