The original Juno was coded in 3DRAD by Rodney Smith......though had lesser quality graphics, was a lot easier to play. I'm lookin forward to the new Juno Remix.
That is looking very good. Makes me want to go and play "Gyruss" or "Beamrider". OK the fact that my C64 is not connected to anything and hidden under 3 cm of dust makes resisting that urge a bit easier. Anyway your game looks like it is really fast.
