Very fun the way the arrows and quads interact! Also, a very intuitive and practical puzzle to explain and illustrate the phistomefel ring.

I didn’t know what Phistomefel was so thank you for an easy (and fun) introduction to the concept.

My first Phistomefel style puzzle. Thank God for Simon, or I would have had no chance at that.
