Jakob: Nice concept, very freaky and scary in the beginning. A little bit hard to understand in the beginning (that you should actually look back instead of not looking back). Has some issues, with the sticky keys on windows - but that only adds to she scariness. Also would greatly benefit with some variation, as the longer you go, the enemy had a very repetetive pattern which was easy to predict, therfore less scary. Overall a nice thing, that you should definitely work on in the future :)
