What to buy with about 1,500 Yen in PSN gift cards

[Creamy Goodness]

Recently got Esp Ra.De and Sorcerer Striker off of PSN, and now I have the balance of money on the gift cards to spend. Any suggestions on what to get? I have every shmup I would want from the US store, but not sure if there are any JP only games worth picking up. Outside of shmups, something like a good platformer or run-n-gun would get my attention. Would be nice to get something JP exclusive, but if there is nothing worthwhile I can just get the JP version of something released in the US.

If you have a ps3 and Japan account try Harmful Park maybe or Yuuiin I think it's called. It's kind of odd vacuum riding shmup.
