Sumioni saw release today. Acquire wasted no time in announcing a patch for the Vita title.
In the coming days, the game will receive a free patch that adds two modes, a Gallery Mode and a Ranking Mode. Gallery Mode lets you view the visuals and listen to the music that you encounter in the game. Ranking Mode is a nation-wide challenge to see who can clear the stages of play the fastest and while taking the least amount of damage.
Acquire did not give an exact release time frame for the patch, but you can see some screens here.
