Also: here's a very simple Logo Adventure I wrote: my first paid commercially published code. Terrapin wanted an example of a Logo program that demonstrated how to use list processing and functional programming, and they included it on the Terrapin Logo disk for the C64. It took advantage of the interactive Logo top level read/eval/print loop, so I didn't need to actually write a parser!
