There's currently a sale on all of Jupiter's games on the Nintendo eShop- which is primarily Picross S1 through 8, plus Kemono Friends, Overlord, and Sega-themed Picross, but there's also this game, confusingly titled "Picross X: Picbits vs Uzboross"
It has a demo out so I decided to check it out, and to my delight, I found out this was Speed Picross. The conceit is that you control a horde of rabbit creatures called "Picbits" that are trying to escape a giant worm called the "Uzboross", and you get more speed for your Picbits to escape and eventually fight the Uzboross by solving as many 5x5 picross puzzles as you can within a set amount of time.
It's the exact twist on picross that I needed to reignite my love for them, because as simple as 5x5 puzzles area, having to solve as many as you can, as fast as you can, is a new kind of engagement. Plus, it works in a ton of goofy little gimmicks, like giving you a fully filled-in 5x5 grid that you need to remove block from to get the answer, or placing bombs that need to be diffused by solving every square in the same row and column as the bomb.
If you're into picross, at the very least, I'd recommend picking up the demo and giving that a whirl.
