And no, it's probably not the one you're thinking of (though that one has an interesting story as well!).
Something didn't seem quite right about this.
Specifically, page 85 of the March 1985 issue of _MacWorld_: archive.org/details/MacWor…
"Steve Capps, the Apple programmer who developed _Through the Looking Glass_ [...] also designed and drew the game's two fonts, Alice-12 and Cartoon-12."
A font from an early 1st-party Mac game made it (questionably?) onto some Mac shareware disks.
A programmer at EA found it, converted it, and included it with Deluxe Paint.
From there, it then appeared in a lot of other games whose artists used that program.
