@jsiehler nice! I'm struggling even with some of the easy ones, though. I need to come up with some lemmas, I think.
It would be helpful if the target positions were always shown somehow

@christianp Thanks! I struggle with solving these too. Starting position and ending position are shown in the mini figures on the left and right.

@jsiehler ah, those aren't visible on mobile

@christianp Ah! I'll work on the layout, then.

@christianp Yay! Thank you. "I made it onto The Aperiodical" is going on my faculty report this year.

@jsiehler I hope your employer values appearing in The Aperiodical higher than mine does running it...
