Nonograms Prophecy is... a bad Picross!
It was free in a recent deal, and it's Picross, on the Switch, so I'm playing the heck out of it in spite of these flaws, but they are really bad flaws.
First off, you know the thing a lot of these do where they grey out stuff as you get it fully filled in, like
This one will do that, but it does it badly. If you have like a column that's like, 1 1 2 1 1 1 and you have filled in the first and last 1, it will grey out the first two 1s. Fill in the 2 later? It might leave those greyed out, not making any sense. Or hey, maybe it will un-grey one, and then never get around to greying it out again, even when that whole row is perfect. Really throws you off something fierce. And I swear there's some where the outermost numbers get clipped off the screen, AND the shade of grey it uses for greyed out numbers is close enough to the background color that it's quite easy to say, fill in the top row all the way across, and then start mis-filling the second row because the top row indicators are now in visible.
But what really got me stomping over to this thread is that after a while you unlock a color mode. And hey, I enjoy color modes in my Picross, those are fun... except oh no now the grey-out indicators are bugging out even worse due to whatever coding error is at play there, AND the palettes are never like, here are several primary colors. They're "here's 3 different shades of grey or red or whatever" which... turn into different colors when greyed out. Sometimes these greyed out versions look like the non-grey versions of other colors you're using, or are darker, somehow.
And YES on top of all that it totally does the thing where you hit a point where there's a coin flip on which of two pairs of pixels you fill in in multiple places so you have to do a bunch of trial and error. And not even like "well it's clear what the picture is going for" no like literally guess which way this otherwise totally symetrical thing has some corner deco oriented. Argh.
