I've thought about it several times.  I haven't yet started messing around with the 7800, though.

I think it's a much needed title to add, especially if it supports the 7800XM.

I would have liked to see it on the Colecovision.

The original company that owned it, I believe sold it to another, and that company went defunct in 2014. I'm not sure if anyone even owns the rights to CC anymore? If they do, it would probably be in a Japanese holding company. Of course making it a little more work to sort out if it would be a problem to even make the game by name, or call it something else. Building Climber? Unstable Climbler? WTF is that man doing? Climber.. Well you get the idea.
