Hello everyone! I'm excited to share with you the latest update for my nonogram game, which includes some great new features to help you solve even the toughest puzzles. First of all, I've added a new option to mark cells in the grid to help you keep track of which ones you've already figured out. This should be especially helpful for larger, more complicated puzzles, where it can be easy to lose track of which cells you've already solved. Secondly, I've made some improvements to the way the game handles marking cells as empty. It should now feel more natural and intuitive, making the whole puzzle-solving experience even smoother. Finally, I've added support for undo and redo functionality, so you can easily go back and correct any mistakes you might have made along the way. This should be especially useful for those times when you accidentally mark the wrong cell, or when you want to try out a different strategy without having to start the puzzle over from scratch. As always, I encourage you to report any bugs or issues you encounter while playing the game. Your feedback is incredibly valuable to me and helps me improve the game for everyone. And to those of you who have already shared your experiences with the game, I just want to say a big thank you! Your support and enthusiasm mean the world to me, and I'm so grateful to have you as part of this community. Happy puzzling!
