Excellent job, this was very fun to play. I liked the explanations, graphics, interactive tesseract, all nice attentions to detail. How much guidance did you give Astra? Did you give a single prompt, an example site to mimic or was there more to the design and make process?
"Create a single html file 4d chess game. By 4d it means 4 dimenstional space. It needs to be playable with understandable rules."
It created the working game with the four boards but since it was impossible to understand from just the board I told it to add a Tesseract.
