Lots of Nonogram Fun, with Great UI – Paint it Back Review

I was looking for a fun nonogram puzzle game and I've found it in Paint It Back. In the game, the puzzles correspond to pictures (often humorous ones). There are 3 difficulty levels for most puzzles (all the hardest ones have options for lower difficulty). The UI allows for easy switching between checking and filling in squares and also tells you when a row/column is "full", without immediately telling you when you've made a mistake. The game comes with up to 6 profiles, so multiple persons can each have a go, without ruining anyone else's experience. I tried two other nonogram games for iPhone before this and this is my favourite so far by a mile.
