I was looking for this game everywhere and I only got the test tape, at least where I was looking...
So, with the kind permission from DomReardon, I will upload the full game with the final boss here.
Enjoy!

So what's the story with it?
Well I did port the demo to the CPC with kukulcan fixing some stuff.
Later he and some people made the full version.
Just love this game and couldn't find the whole thing.
So, here it is.
