Thank you! We did spend a lot of time researching everything that came to mind (like their national board game, known as "the royal game of Ur". Sadly, we don't know its akkadian name, otherwise we'd have mentioned it in the dialogue. I slipped its board in the cutscene background, though.)
I loved Chants of Sennaar! Altough I can't cite it as inspiration for the game because backgrounds and the general palette were done by my teammate.
Yes, I did notice the choice box gets weirdly distorted, but I have been unable to properly fix it so far. And, don't worry, it bothers me too.
