Argh, my eyes started going funny after level 11.
@Kat, your remark inspired me to work through up to Level 12, and I concur that eyes and motivation both seem to give out at about that point.

A way of dragging whole clusters and of reorienting them would help. Fun game once through as far as it goes tho’.
OK I think level 18 is my limit.
