The Colecovision takes any standard 9-pin Dsub connector joystick/paddle compatible with Atari/Commodore so that shouldn't be a problem...
As an amateur Colecovision collector I'm actually quite interested in this. Who cares if it's not a designated CV game? I'm just glad that there is such an active CV community that still produces new cartridges with game. Bashing a platform because it "shouldn't have this-and-that-game" is something from the 80s (Amiga is better than Atari anyway

)
Reservations can be made via the AtariAge forum:
