Hm, noone has replied yet. Have the developers already started coding silently..? 
I had a look at the game. It's pretty good designed and nice to play (although it's just a shooter). It's quite amazing what the imagic folks squeezed out of the Atari 2600 in 4k of ROM. But As far as I know, the architecture of Atari 2600 ("Stella") and C16/Plus/4 is very different. Stella has sprites and needs programming very near to the video chip while with C16 one can only use the text screen with a self-defined character set or hires programming, but the latter is probably too slow and would use too much memory on a C16. I had a look if there's a C64 port of demon attack but that is using sprites, too (see http://www.gb64.com/game.php?id=2104&d=18&h=0) and it's quite ugly, even though the programmers had much more memory.
I found that there is also a VC-20 port of demon attack done by imagic, too (see http://www.youtube.com/watch?v=xCPHm43WfDE). This one should be architectural quite similar to what it would be on a C16, because a VC-20 has no sprites. And in the youtube video it looks very near to the Stella original. Maybe there's some folks who are experienced in VC-20 programming and might want to port it.
