YES let's go, what an insane level. As if getting to the end isn't hard enough, the optimization is incredibly difficult here. So happy to finally see the idea and get the solve!
Really struggling to optimize this one. So impressive that you packed so much puzzle in such a small reason. The possibilities make my head spin
Got it down to 256! What a remarkable level. For me, the last 10 was the hardest. There are some parts where you have to be really careful. Excellent level!
Another excellent level! I got quite badly stuck at 268 (and have all sorts of longer variations, as well).
Will keep trying.
EDIT 20th Sept., 2023: I finally found a way to do this in 256 steps. Excellent level, indeed!
