Hi Jonas, thank you for kind words and feedback. I am glad you like Quasimodo's Christmas Caper. I've enjoyed making it and glad to hear it now works fine on your C64 mini. It's sometimes difficult to support these newer C64 devices as I don't own every one of them, however, any issues feel free to let me know and I will always try to see what I can do to fix them.
Look out for Release 5 of QCC which will feature a new game ending, some more improved graphics, bug fixes, extra music and sound, and a tape version of the game with loading screen. Thanks again!
