Excellent work! I've spent so many weekends as a teen, typing in games like this into my C64. I really like the idea of incorporating the use of the mouse. This is probably my favorite Klondike game on the C64.
Wow. Thanks a lot for this nice feedback. I initially looked at other C64 Klondike games and thought that can be done better (and with mouse). The tricky (and fun) part then was to make it fit in my 3 A4 pages listing limit and that it plays fast enough in BASIC. Was a great project.
