KnotBot

"KnotBot is a single-player simulation game offering around 2 hours of playtime. As a KnotBot programmer, solve handcrafted puzzles using knots and yarn-balls instead of text and numbers. Experiment with unique mechanics in different areas, each containing a series of puzzles with cute aesthetic graphics and a relaxing soundtrack. Challenge yourself to solve puzzles under a certain amount of moves and collect all the Golden Socks for an added challenge."
