Also have very fund memories of Humbug and Jacaranda Jim (wow it took me a very long internet search to find the names.. I forgot almost everything about what those games were about, and all I had to go on is that they were DOS executables and that the author was some anti-virus author).
I love seeing Adam Cadre's name in the wild, I know him through the Lyttle Lytton contest that he's held every year since 2001. It's a fun deep dive of terrible (on purpose) writing. https://adamcadre.ac/lyttle/
