Surprisingly tricky to see actually. There’s a lot of options, and even though most are clearly unviable, it took me a bit to actually find the right one. A bit messy as levels go, but interesting to solve nonetheless.
LOL, funny one. Got it on 2nd try thanks to noticing before starting that a simple and straight up and down consumes already 16 steps, so more than the half... That was the key for me.
