Touch Arcade: Huebrix [$0.99] is a frustrating game to talk about. I want to tell you all about its puzzles, which are good and clever and rarely aggravating. I want to warn you about its flaws, which are found in nearly every other part of the package. I want to say it's a great little game, one that could scratch your hypothetical Picross/nonogram itch almost perfectly. I want to say it's poorly designed in every way except the one that counts most. Buckle up, in other words. Things are about to get messy.
