Quite a good move for Spike separating the game which will be available for purchase, and if you just want it straight on you can just download it for 2000 yen. The game's been popular in Japan which debuted a few years back and has a similar game play to Ace Attorney with a mix of Bullet Hell Shooter.
If you're at lost you can take a look of what the game play is from it's trailer in YouTube. If you're proficient in Japanese then you might be interested in purchasing it when the right time comes. On the other hand there's Marvel VS. Capcom 2 on the iOS readily available for download if you find yourself incapable of reading Japanese characters.
