As a crossword fan and math teacher of over 25 years, you get my seal pf approval.  (Like that counts for much  ;) )
Well done!

happy pi day! so much fun - i really enjoyed this one. loved the video game references (zelda, fire emblem) - when i filled in "max" for parabola i was thinking what if the parabola is oriented the other way! and then i saw "min"... genius! thanks for starring the rebus clues too

Thank you! I'm glad you liked those, I'm never sure who will get the references. :)

I got a decent chunk solved before it got out of my league. Nice puzzle - I'd say you succeeded at your goal 👍👍

Nice one! My cat is definitely a SLEEPER 😹

This is great ! And lots of cat related clues !

That was a really fun puzzle dense with themed clues.  Had a bit of trouble with the NE since I mistook WAN for NYA (i.e. cats for dogs).  Thanks for sharing!

Good recap to the year Ernie! Here's to a better 2021!

Excellent puzzle.  It's hard to construct these densely themed puzzles without a bunch of cringey filler, but this is solid (and nicely clued) throughout.  Well done.

Great puzzle. Really loved the clue for JKL -- that one was new to me. Thank you for sharing.

Fun puzzle, super-clean fill, great recap to 2020 overall!  Thanks for sharing.

Thanks for the timely puzzle.

Great puzzle Ernie - tricky but fun! 😊

Lovely grid! Really appreciated the theme - only caught it towards the end, but it helped plug in some gaps and brought a smile :-)

Great puzzle. Loved the themers, especially MONSTERSINC! Thank you for posting.

Cool theme! I couldn’t quite get them all but definitely enjoyed it 🦇

Thanks, this is the first one I made utilizing the site's autofiller!

Nice! LMK if you have any issues or suggestions with it 😁

Wow that was a lot of theme! Really enjoyed it!

Awesome puzzle DiamondFalcon! The jokes were funny, but I also liked your original clues (STPAT, STALE, and IGOR were all great).

Also 51-Down should say 'tall', not 'talk'. Sorry about that!

This was super fun! Loved how even short answers were part of the jokes.

Nice! The GOOUTSIDE joke feels a little different in these strange times. 50-Across was my favorite clue.
