Fantastic thread DJC - been so looking forward to you re-releasing this game - it surely rates as one of the best Amiga Shareware games of all time - which is an incredible achievement when you consider just how many Amiga PD and Shareware games there are!
It's so great so have so much information about the game - if only more authors would get back into the Amiga scene!!
I think the idea of donating to charity is a fine idea and you have certainly picked a very worthy cause.
A Big Thank You for taking the time to share your Amiga stuff!
I have updated "Scavenge Amiga" Facebook page with details of David's Fund-Raising web page.
