Suggested solving music above. I’m a big fan of Popskyy, and not just because he explicitly allows his music to be used in streams. Chiptunes 4eva!
This puzzle was an absolute bear to fill. Typically the acrostic generator can find fill for an acrostic in well under a minute. This one took around five minutes to produce fill each time, and I had to do a few passes to get fill that I liked. I’m not sure why — maybe this is at the upper limit of a grid size you’d want with this few source letters? Anyway, I think the end result came out pretty good.
