I want to like this game, but so many of the QOL features in other nonogram games are either not here or the opposite of what you expect. No zooming in on large puzzles. You lose hearts for both misplaced squares and Xs (all other nonogram games let you use Xs as placeholders and don't penalize you for misplacing them). You only get 3 hearts per level instead of 5, which when combined with the lack of zoom, makes it easy to fail just on misclicks.
