Bought the physical C64 version, and I just started playing it with my wife (It's her first text adventure). She's enjoying it a lot, which says a great deal as she's not a video game person unless it's Columns or PuyoPuyo. Currently at the part where we got the reply telegram, and have some stamped paper. Really good map, very logical.
Does the save system save to the disc, or do I need a separate disc to save on?
