Current version's disk image ist called V2.1 but title screen shows V2.0. Is the download correct?
The "Make your choice" selection is misleading in my opinion. Maybe just a leftover from earlier builds. "Select a solved cave" or something like this would make more sense to me. And maybe the "make your choice" text above the selections (would require the treasure pile to be moved higher and might make the screen to crowded).
Title screen music has strange wobble sound at some places, more audible on new 8580 SID environment. Not sure if this wanted.
There is also a small pause in music play when switching from title screen to cave show.
