I finished Opus Magnum a couple weeks ago and I found it a little frustrating because of the same reasons you brought up. The game doesn't force me to be clever; I can be as simplistic and inefficient as I like. I did go out of my way to design a couple efficient designs, but it didn't feel especially rewarding.
FWIW, my favorite game from them is Last Call BBS. It has several great "mini"games that feel rewarding to just complete.
if you don't enjoy them, then you've at least had a sizable taste of the mechanics and know why it's not your thing, rather than getting hard-blocked early on because you couldn't figure out a trick :)
