Overall a very interesting experience, though there are areas for improvement, particularly in terms of grammar and spelling. With such heavy focus on interaction with the "entity", it is quite immersion breaking when the dialogue has noticeable errors.
I think it's fair to say the game drew quite a bit of influence from Imscared, which is fine; I think you did enough to differentiate yourself so that it didn't feel like a re-run. There were some areas a little too on the nose; the chair and noose and the heart doors being a noted example, but as I say, overall it was different enough. All things considered, a neat little experience, albeit one that could have been a little better with some extra polish.
