You're absolutely right. I should have done and am sorry for the difficulty it caused you :-( I uploaded the game moments before the deadline and it was only afterwards I realised the issue.
I'm afraid this was the first thing I've ever made on the Amiga (or outside of Flash or DVD Studio to be perfectly honest) and the two weeks was a sharp learning curve. I still have a lot to figure out, so mailman, if you care to enlighten me in creating such a script I am eagar to learn. Otherwise I'm afraid all I can do is muddle along until I figure it out myself.
Thanks again to Cammy for creating this competition and inspiring me to try something new.
