nta but I LOVE weird custom-campaign shit like this, stuff that not many people will play but is absolutely jam-packed with effort and unique stuff.
Now that you posted this, it reminded me of a similar thing for Portal 2, A Minuted Millions:

I recommend going in blind, great stuff. Playtime is roughly 1-2 hours, single map (kinda).
