A playable demo was released on the Japanese PlayStation Store in June of 2015. It includes two stages, playable in Arcade and Classic modes as well as a handful of the game’s many Challenge mode stages.
A persistent ranking system allows players to unlock new challenges and items as they replay stages. The score at the end of each stage is directly applied to the player’s rank and can be boosted for completing certain criteria like not using any continues.
An auto-save feature even allows progress to be made in the demo which will presumably carry over to the full game.
The title card at the end of the demo states a new release date of December, 2015.
