I wish there were more games like this. It’s such a simple premise but so satisfyingly difficult after each level. And it even has a bit of randomish failure which makes for even more challenge.
If you buy the adorable monochrome console called the "Playdate" https://play.date it comes with a bunch of games included, including a cute elevator game where you help penguins to different floors while controlling the elevators yourself using the crank:

That's the guy who created Infiniminer, which was essentially 3D multiplayer Motherlode (a game everyone was playing at school lunch and I never figured out why) and inspired Minecraft.
Wow, I just came here to comment that I've always wondered if a game where you have to program an elevator scheduler would be any fun. I thought surely no-one's thought to make that before, too! Glad to be proven wrong.
