Thanks for the feature suggestion! I've gone ahead and implemented random valid stacking order. So if you reload the page, and enter text that repeats the same letter more than once, you will hopefully get different build orders (depending on random choices). For example: https://erikdemaine.org/fonts/tetris/?text=aaaaa&rotate=0&sp...
