Weird PC Engine Game ...

I played a really weird game at Katsu Con. It was some Beta game that was 
never realeased. Only the first stage was complete. It had the graphics 
engine of Space Harrier and the Character Design of Fantasy Zone. Anyone 
know anything about this game? What is it called? It was pretty kewl. How 
hard is it to get ahold of this item?
