The trailer is eligible for being nominated. The actual nominations don't happen until January 2018. Still pretty cool though.
I don't know what's going on, or what it's trying to tell me the game is about. But I must have it.
The movement of all the characters is by somersault?
Not all, some models moved by morphological transforms, e.g. flapping wing textures by sinusoidal excitation. I presume it's that it's fairly quick to build a model, but extremely laborious to animate it. For a game that features "everything" I think I can let it slide. :-)
