Ok, it's an old C.64 game. Maybe released about mid-way through the 64's life span.
It was a futuristic sports game set in an arena and had a side on view of two little guys standing on floating discs. You can move side to side or up and down. You could shoot a ball into a hole that was actually the mouth of some robot thing. You could knock your opponent off his hover-disk and kill him too. I've been really trying to remember the games name but it's completely gone from my memory.
I have a selection of retro games up for grabs for anyone that provides me with info that identifies this game. Please help me.
