Oh no!! I'm so sorry, I'm not sure why this error happened! If you'd be so kind as to report this on my error form right here, it'd really help me try to replicate and troubleshoot the issue❤️ Thank you for posting about it so that I'm aware of it though! And sorry again, errors are no fun to encounter:/
EDIT: Okay, I found a couple posts about this error (here's one, and another) explaining that this can appear when cookies aren't enabled on your browser. I'll update the game description here to say that cookies must be enabled to play:) And thank you again for reporting this, I learned something new today!!
