As the number of blocks increases, the memory consumption during rendering also increases substantially. To address this issue, I would recommend implementing memory optimization techniques, such as the flyweight design pattern.

I have already implemented a similar solution using the flyweight pattern in my repo, which you can check it out. Additionally, I highly recommend checking out patterns.dev for more information on the flyweight pattern and its benefits.

By implementing memory optimization techniques like the flyweight pattern, we can significantly reduce memory usage while maintaining the same level of functionality. I hope this suggestion helps to improve the performance and efficiency of your project.

Thank you for considering my recommendation, and have a great day!
