For the first game in a series from a small studio, it's pretty polished.
The environments are gorgeous and hand crafted. I have enjoyed the non-linear/exploratory aspect of the game.
Combat's fun and when you get a combo just right and slam an opponent into the ground (or get slammed yourself) you definitely feel it.
Would highly recommend starting with Wulfgar as the first character you try out. Definitely the strongest solo character and, from my experience, the most fun to play.
Excited to see the series improve with each iteration.
