I, too, grew up on the first-ever Zoombinis game. I actually recently played through it again almost 15+ years later. Everything from the sound effects to the visuals is seared somewhere deep in my neural wetware like a permanent ROM chip. Funnily enough, some of the puzzles still confused me! I guess my colorblindness certainly hasn't been magically cured over time...
Thanks so much to OP for linking this article.
