Planet Virtual Boy

Has anyone heard of this obscure original Gameboy game?
I have this game I got it for about 6 dollars (and its the only one I've ever seen on ebay )
It was cartridge only but it is in good condition
and apparently is really really rare and there isn't much information on it but it does exist and it is a real release
heres a video of its gameplay: http://www.youtube.com/watch?v=yaA4ORYCNl4

I wish I could get Virtual Lab, Virtual Bowling, SD Gundam Dimension War or Space Invaders Virtual Collection for 6 dollars

I wish I bought a box of SD gundam for 6 dollars a game. I'd be rich ;p
