Pick Up the Ice Cream Truck and Die was written in TADS, and is © 1998 by Myn Duespo.
This solution (such as it is) is by David Welbourn.
This "game" is just a test of the HTML TADS's ability to play MIDI sound. There's not much you can do, and you can't "win" as such, but here's what you can do:
>x me. x truck. x loudspeakers. listen.
>open door. unlock door. x sun. x sky. xyzzy.
>pick up truck. (Note that "get truck" and "take truck" don't work.)
>x fire. out. yell. help. quit.
And that's it!
