Sumioni is one of the most striking and arresting games I've seen in a long, long time.
Last week during the Tokyo Game Show, Acquire's Luke Rideout showed me the game. In the above video, Rideout provides an overview for the title.
Sumioni is still early—hence, the load times.
The game has been called Okami on the Vita, which is a gross oversimplication. Check back later for Kotaku's impressions.
