Later today around noon, Final Fantasy Legends Crystals of Space-Time will be releasing in Japan. The game is free to play on mobile devices and will have players do time traveling which has a similar feeling to Chrono Tiger. Music is composed by Naoshi Mizuta (水田 直志) who worked on other Final Fantasy titles like XI, XIV, XIII-2, and much more. Here's the trailer.
