Zombie, Run! Zombie Finder
The first of the two games is called the "Zombie, Run! Zombie Finder". It is free and open-source software. The project founder is Peter Dolan.
According to an old comment by Reddit user "participating", it is:
[A] fun way to get some running/jogging/terrifying ...
I just posted this question and self-answer. Are they reasonable?
@unforgettableid Fine by me at least. Could you add the links for those two games in the question itself and you may consider removing that disclaimer about self-answering? It's not really important since others may also attempt to answer your question.
@Firelord Congrats! What isn't quite clear from your answer is how it matches the question: where is the nesting there? Raw guess: some icon from the 1st screenshot is that Tasker shortcut to open the scene?
@Izzy The last icon in the first image named "Nest" is the Tasker shortcut. I actually mentioned it in the very first line that scene is loaded using a shortcut which is created from Task shortcut widget.
@Firelord Yeah, saw this line. What's missing is the connection. It doesn't become clear that that shortcut is placed in the "top folder" (that folder icon was my guess, but its name made me unsure :)
"[…] and created a shortcut using Task Shortcut widget to launch the scene (see the folder icon titled "Nest" in the first screenshot)."
That would make it perfectly clear: You've placed that shortcut in a folder, and thus basically nested it (ah! that's the reason for the name – not some thermostat :)
Sorry, but "Nest" has so many different connotations :)
