I've played Bonechiller Burrow and Forest Temple, and, man... those bosses are way harder, specially the one from Forest Temple. I enjoy both of them, mainly because they are longer, and that Ice-themed level is very well made. hahaha I'll play them a little bit more later, because I got obliterated by the bosses.
Indeed, I should reduce the shake camera effect. I am very clumsy on editing cinematic, because I generally start to add something, then I stop in the middle of it and change to another part.
