To clarify, I am not the author of Bobo. JamiK is. I found an old email from 1995 that details my contributions, though:
"I revised Bobo add-on for ZZT. I removed a few of the flashey-boarders because they make you sick if you play for too long. I wrote a new title screen (looks better, but has same info). I changed a few other things, but only for the better, like adding music at the party."
Despite Kev Vance's graphics fixes, this game is completely devoid of programming. Through use of scrolls, however, a rudimentary plot and some juvenile atmosphere are built. It was kind of odd how articles of clothing were about 10 times as large as the player, but that's to be expected when virtually no objects (and absolutely no programming) are used.
Reminds me of my newbie days, when I would put a scroll next to a colored solid that was supposed to represent a character. Ah, those were the days.
