While their game has been out for over a month now, Acquire are still out there developing and promoting their release of Sumioni (Sumioni: Demon Arts in the English localized release). The first half of the trailer is dedicated to promoting the title and its action-platforming gameplay which uses the all-mighty power of ink to aid you in your quest to save the world. In terms of updates which I assume is the main purpose of this trailer, Acquire has just recently introduced a Ranking System and Gallery Mode to the game… both of which are general things you would expect in a game like this so it is good they have finally been able to include them.
The game is due for release in North America from the folks at XSEED Games on the 20th March 2012.
