Well, the game was developed by 'Red Dragonfly' [DL-based, 'Aka Tonbo'], and prior to this release, he made 3 other games with near-similar gameplay and experience:
- Pandemonium 'Slash Princess SAKURA'

- Sangoku Musou 'Empress of Tragedy'

- and another game, 3D SmhUp-style that, unfortunately, I lost memories of...
Fortunately, both presented here were probably the latest available than anywhere else's; unfortunately, both were also quite a bit old as they were never updated [they were finally updated in DL site - as such as you can play SAKURA in 'Sangoku Musou' game]
