I just gotta say that it has a very solid foundation in almost all aspects.
It tickled my artistic side and made me think of ways the mechanics could be implemented, like for example having a sort of vampire/blood bender being that could explain away the way the mechanics are implemented and make the game more engaging story wise (although boomer don't need a story all the time, this could elevate the experience).
The parkour is the right amount for a fps and it was well done. I loved the floating monks as well.
