Usually I'm not a big fan of AI animations because of how uncanny, unrealistic or, on the contrary, overly "realistic" they look. In this game, however, animations are stylized, simple, fluid, extremely hot and don't tap into uncanny valley territory at all. Best part: there are hundreds upon hundreds of 'em. Each update throws in a couple hundred more, and those updates come out at a surprisingly rapid pace.
I did not expect to like this one, but it somehow hooked me and now I love it.
