Your exploration of using the Chinese Civil Service Exam as a source of inspiration for designing puzzles is a unique and innovative approach. It's interesting to see how an exam known for its rigorous testing of logic and knowledge can influence game puzzle design, especially with the emphasis on visual and logical elements. The transition from being inspired by a question involving many triangles to incorporating polygon sides into your puzzle design showcases creative thinking and problem-solving skills.
The idea of integrating visual patterns, like the butterfly pattern from Zimu's idea, into puzzles adds a layer of depth and engagement for players. It's commendable that you actively sought feedback and were quick to address the bug identified during testing. Incorporating hints within the game environment as collectible items is a clever way to enrich gameplay and encourage exploration.
As you continue to design more puzzles, it would be useful to hear about any new inspirations or methodologies you're considering. Additionally, how do you plan to balance the difficulty level of these puzzles to maintain player engagement without causing frustration? Your approach to puzzle design could offer valuable insights for others looking to create engaging and thought-provoking game content.
