Five stars, excellent work! This was really, really good. New mechanics to keep it interesting, just the right amount of player leading, an interesting world that felt right and a very satisfying ending. Really well done I loved this game.
Some notes: I double turned frequently and (I know this has been covered) the camera felt too close to the wall. Also I found a bunch of stuff I didn't use. I assume this means content was cut but it felt out of place regardless.
