I really enjoyed this! Releasing little holiday specials is a really good way to get interest in the series and do good Alpha Testing. One thing that seemed wrong was the sign next to the wall of hands that said "Shift to walk faster", when it actually makes you sneak. The lever puzzle next to that was also a bit difficult to see properly. Apart from that really good and the best bit was the reveal of the boss and how the levels flow seamlessly into each other.
