This level got recommended to me again today. I can finally see a better way to do it. I got a 183 and was worried that I might be quite stuck. But in my case it was due to a wrong exit choice.
Actually pretty neat solution from Carl, I really like how that one works out. I feel like the level could have been constructed to be a little more interesting, but it's not bad.
Some blocks are underutilized and could have been brought into the puzzle with a few tweaks. I love the idea here but I would prefer it more focused, or with those blocks incorporated properly.
A functional demo of this idea. Nicely avoided any esoteric pipelining and mercifully kept it to three holes. Just right for an introductory level, really.
