OMG! Jetpack from Adept Software is still available?! https://www.adeptsoftware.com/jetpack/
And the lost mind/island of Dr. Brain.
I wish I could still play them!
They have Lost Mind as well, but not emulated because it's a Windows game. I wouldn't be surprised if it still runs, though.

It's extremely faithful to the original in terms of "feeling", to the point where it satisfies my TIM nostalgia
Looking up images of DOS platformers like Secret Agent and Crystal Caves reminds me of a game that was loaded on some elementary school computers in 1998. I don't recall if they were Mac or DOS, but they certainly weren't the cutting edge G3. I think the game had a character in a trench coat and they were maybe a sleuth of some kind. The color palette was dark but there were yellow-ish lights coming from above in a conical shape.
I know memories are usually warped and wrong, but hopefully this is enough of a description to jog someone's memory. I have been able to rediscover all of the games I played as kid. Most I never revisited, but it feels satisfying to learn what they were. Big ones that bugged me for ages are Tyrian and Descent.

edit: This DOS game might be the one you're thinking of
I think it is likely an Apogee game or by someone inspired by their art. I haven't found a solid hit of what's in my memory after looking through their catalog and a quick glance through a wider list. It may just be busted memories and it is Secret Agent. It's unsatisfactory though because every other vague memory has turned out to be more accurate than not.

Abuse had that crazy scriptable level editor, I must have spent more time in it than actually playing.
I don't know of anyone else who's tenure in the industry is 30+ years.
Sometimes I hang out with my little brothers on Discord, with one of us playing DR (or a similar game), the rest watches the stream. We have some snacks and pretend we travelled back in time to the era when we shared the same PC and had a (very elaborate) hot-seat queueing/watching and commenting system.
"streaming" as watching your buddy play in the same room beats Twitch for me every time!
Recently I had fun with The Curse of Monkey Island and Microsoft Bob experienced in the same way. Although the latter is more like bringing your friends home for a Tommy Wiseau movie night.
I love that game!
It made a generation who can code!
