Great idea and implementation, especially given the time constraints! Though I may be biased since I'm a huge fan of all things Mesopotamian XD
I too watched the British museum video and wanted to try playing this with a friend, so thank you for making this possible :)
I echo other people's suggestions of adding a tutorial. Another small recommendation (even if it's not historically accurate) is to make the rosettes a different color. For new players, it's a bit confusing that those let you roll twice while the other symbols on the board are purely decorative.
