Thanks for sharing it wonderful game. Just tested it on the latest VICE and i sadly have to report, that the joystickinput isnt working (at all). Keyboardcontrol works semi-OK'ish.
Thanks for the report, you were right! The game was reading the wrong CIA register, so it only saw joystick port 1, and some keys leaked in as input. Fixed: it now reads port 2 (and port 1 too), and the keyboard no longer interferes. Download v1.1, please!
