Hello, newcoleco!
Several months ago you programmed a ColecoVision version of my old Vic-20 game Tunelayer (sheesh- I programmed that game 16 long, long, years ago, in those great days of Dutchess Community College- 16 years ago already!).
How is it now?
If it is completed, feel free to include it on a ColecoVision cartridge.
