The visuals are consistent with a WIP game engine. I can't see why someone would go to the bother of creating a rough looking mockup to showcase animations in a non-existent WIP game. Animation tests are performed economically in barren test-cases, then dropped into the game. The 3 step cover where the character drops to a lower animation position each time is evidently a test-case, and the odds against this strike me as very slim.How do we know it's realtime?
