April 4, 2021: themeless 7
One reason I like making indie puzzles is because I can make the grid look like whatever I want. (Another reason is because I can write clues that are 239 characters long.) This grid is 23.55% black squares and I think it's very beautiful. It doesn't *quite* have diagonal symmetry, but it's close.
Many thanks to Neville and Rafa for test solving this one!
