Many thanks to RockyRoer. I've updated X-po and re-estimated the listed difficulty

Lots of fun for x-sum lovers! Just over two hours total time for me. My favorites were the renban, arrows, and modular puzzles. I struggled a lot with the Kropki, if it's really 1.5 stars, I missed something obvious. I'd say all of your difficulty estimations are a slightly low, to be honest, except x-tended.
Thanks for sharing them with the world!

Very nice! Requires a lot of calculations, but I guess that's the nature of it. Every puzzle had a unique insight. I actually felt like they were all about the same difficulty, but maybe that's because I got used to this type of puzzle after solving them in order. Every one took me 10-20 minutes. The only exception being the renban one which was so smooth, I solved it in 4 minutes. Thanks for sharing this small pack!
