Unknown Origins of BASIC adventures

[Strident]

There are various BASIC text adventures in the database that probably started their life as type-in listings but, along the way, have been credited to other people.

So I'm just putting some gradually in this thread in case anyone spots any similarities between other games or later comes across the original type-in or source.

For example this one...
Time Warp

Which was previously down as one of Dorothy's games, but the game title page itself says "Author Unknown" and "This version by Dorothy Millard".
