Late to the Colour Maximite party with this one. First basic game I've written in many years. It's not pretty but it works ;) - Anthony Clarke
Zip file attached has all the files you need.

Keyboard only at this point. I'll add keyboard support just as soon as I get a port soldered onto my CMM to test ;)
Just remember PS/2 keyboards don't like multiple keys pressed at once and you'll be fine.
