Considered taking one star off since it would benefit having a larger puzzle area and would be improved with a monochrome and dark mode background for better contrast. **Developer response:** Thank you for the great feedback! We’re really glad you enjoy the Notes feature. Based on your suggestion, we’ve added a new monochrome background option for better contrast, which can be switched directly while playing. Thanks for helping us make Binary Logic better! - Francois ## Frequently asked questions about Binary Logic ### What is Binary Logic?
