NIS America has confirmed that A Rose In The Twilight will be available on the Vita from April 11th. A Steam version is also expected around the same time. The game is from the director of htoL#NiQ: The Firefly Diary, Masayuki Furuya, and the visual style certainly mimics that game in some ways. In A Rose In The Twilight players take on the role of Rose and a giant as they try to work out what happened to the castle they’re in. Rose is afflicted with the Curse of Thorns, which allows her to absorb and inject blood to control time.
The giant has super strength allowing it to move objects so the pair can move forward. The game will require puzzle solving to advance through the plot.
