Factory Funner arrived from Kickstarter and has gotten a burst of play in the last week. I'm not sure it's any funner than Factory Fun, but Factory Fun was already pretty great, so it's not much of a ding.

Definitely a fun little puzzle game.

Personally, I don't like the rule about disallowing infinite loops and will in general lobby to allow them; I don't think the prohibition improves the game and there's something delightful about a partial or complete infinite loop.
