Samwise Gamgee absolutely hoodwinked you on this one Frodo, but overall it was extremely fun to play. Actually involves some really intricate pipelining? Are there multiple solutions to this? The one I tried and got first try was actually really cool though! I like the top left puzzle a lot. 5 stars for that.
Rest isn't necessary in my opinion. Liked the use of the bidirectional here. Dodged the two steps though!
