The ending was a tab on the nose (but I've seen from the other comments that there is more than one of them?), but the build up to it was great! 

-- spoiler alert ahead--
I was thinking the whole time that there would be a jump scare or a curve ball like, something was going to ahead ahead of me because I was so focused on looking behind me the whole time. I couldn't run particularly fast - figured it was intentional until the guy chasing me caught up no bother... now I'm wondering if I should have been able to move a little quicker xD

Overall not a bad little slice of a horror!
