Explore gameIn this minimalist one-line puzzle game, your goal is simple but challenging: draw a single, unbroken line to color in every block on the grid. Plan your path carefully, as you cannot overlap lines or leave any square empty. Start with easy grids and unlock more complex, mind-bending shapes as you progress. Use helpful hints when you get stuck, and enjoy the charming animal-themed interface that keeps your brain relaxed yet sharp.
