I haven't even played this game but I felt compelled to write a comment after hearing the term "shareware". I've not heard that term for years and will play amazin escape later on.
I used to play a lot of games in the DOS shareware era and I remember those days fondly. So as I was naming it "Amazing Escape (Demo)" I had a sudden change of heart and decided to use the old term "shareware" instead :) This version is free and, if there's enough interest, a full version will be produced with all of the chapters, so I feel the shareware moniker fits it well and I'm happy that I was able to use it. I'm happy that it struck a chord with you too!
