Had to use temps for one guess when I got stuck, but totally logical aside from that. Might've just been me being terrible today.

It's really challenging but completely logical. Loved it!

Completely logical

and "using temps" doesn't automatically mean that it's not logical, it can help to visualize logical stuff.

Got it without using temps, but this letter definitely took me a bit longer than most of the other ones. Thanks for the challenge!

100% logical.

Thanks.
