Wow, this game sounds absolutely fascinating! The idea of only using visual communication and exchanging notes across buildings is so unique and mysterious. It makes me wonder what kind of cool text or drawings people would use. Maybe even something wild like a <a href="<a href=" https:="" www.brat-font.com="" "="">brat" class="redactor-linkify-object">https://www.brat-font.com/">brat</a> font for those cryptic messages! Sounds like a blast.
