I wont be surprised if the two games had shared resources, or mutual developers... even the websites are very similar:
http://www.playdead.com and https://playfeist.net/

they even use the same modules on the website, same image browsing, etc... however, hosted on separate servers... still, i think they're directly related.

Actually the development of Feist started well before Limbo.

lol

More than Limbo-influenced -- that dude looks exactly like the main character from Limbo.

A small furry porcupine looking creature claims a human boy is his father and you think age is the problem ^^

He's quite young to be a dad.
