Yes I purchased it.
But ironically about 12 hours after agreeing to the deal, a lurker and fellow X68K fan contacted me as he was able to get the game's image from some Japanese collector. So while I don't have the DVD yet, I've already gotten the game. Waste of money, but meh it's will make an interesting piece for my X68K collection if nothing else.
The game is quite short, and quality wise it's quite a mixed bag (the first boss can't even hit you if you don't move lol), but the music is great.

Oh if you insert the disk in Floppy Drive 0 it will run in 15khz. Insert it in Drive 1 for 31khz. (15khz greatly recommended for scanline goodness)
