Great puzzles, but coloring of squares really confusing
I love this curated list of puzzles, but the UI for coloring of squares is extremely confusing (or buggy). I am able to solve complicated sudoku puzzles, but I really struggle with how to, for example, mark these three squares in yellow, and these other four in blue. Everything else in this UI is relatively intuitive, but not the coloring of squares.
Just the UI for picking a color is weird. I should be able to tap on the three colored circles on the left to change color, but nine times out of ten, it doesn’t change color. (And it has white outline around two colors ... what does that mean?!?) And even when I have a color selected, for the life of me I can’t consistently say “ok, make these three squares yellow.”
Other than that, the game is great, but this feature makes it super annoying, should one want to color squares...
