That was a very cool and economical break-in, which I enjoyed a lot! :^) But nearing the end, I either missed some clever insight or the puzzle just somehow got annoyingly difficult. A bit of a shame really, since the solve was so delightful up until then. Why not add another clue to smooth things out?
~The ending is actually pretty much only two steps, one is coloring the 236's to get 2's and the other is noticing the R4C2 cell being a naked single. I can imagine it being difficult if these steps are not found, but there is an elegant way through. I am sorry that you were unable to find it.

Hm, actually that was exactly the way I did end up finishing. The colouring of the triple seemed a natural step, there is no problem with that. But it did take me a long time to take a closer look at r4c2, which seemed to have two options at first glance. But at that point in the solve, there were a *lot* of cells with that property, so this one didn't look any different from the rest to my eye.

Really tricky at the end, I thought
