Denpa Shonen Teki Game 2 電波少年的ゲーム2

Never heard of this game but looks like it's a sequel to another, common game. I saw it on this blog. (the one posted on 5/3)

Someone commented that it's on this list of unreleased games.

The thing is, they put the game up AGAIN a few days ago and someone's already bought it. Could this be the "Tetris" of Sega Saturn games?

Also, google brings up next to no info on this game either in english or japanese.
