I haven't finished working on this yet, but it deserves a proper review, so:
In all honesty, this is one of if not the best "Ultra Grandmaster" levels in the game. For a long time I was pretty much the only person building stuff like this, to the point that I quite saturated the market and kinda gave up on the idea of making extremely hard puzzles.
A lot of people don't appreciate them, and they're a big pill to swallow, but this level is really a masterpiece from a construction perspective. It has a lot of totally unexpected techniques and it subverts expectations constantly. At first glance this puzzle looks bloated and monotonous but that couldn't be further from the truth. A lot of unique elements are on display here, and they come together quite cohesively to form something that is honestly more of a journey than a puzzle.
I do think this puzzle deserves applause and it's probably your best puzzle (and you have many good ones). I look forward to eventually finding my local minimum stepcount, at which point I will input it and probably walk away from the puzzle regardless of what happens to the record, but it's a really cool and really special puzzle regardless.
I've now spent nearly 13 hours all together, but still can't touch the exit. Still missing two tacos, for the centre in order to make the touch.
This is a really hard puzzle. I hope to be able to figure it out, one day. :)
