Overall great entry!
I felt the tutorial only a slight bit misleading... i thought at first it would be more a parcour-focus evade/kill -second type of game.
I have two problems with the crouch mechanic:
1. The usage in the tutorial is clear, to pass obstacle. But in the actual wave-generating arena, i thought that i rather move as fast as possible.
2. C to crouch? I mean makes sense, but im getting a strong ctrl-vibe here.
All that being said - both game-modes felt like individual games for themselves... would loved more parcour, but the area fight was fun aswell.
And the art is astounishing!
