What a wonderful game!! Loved how the powers from both players are required to solve the mystery and bounce off of each other throughout the whole adventure, and I loved the GMless mystery generation too. We ended up with a fun case to solve while doing no prep - very much recommend, and there's a full review on TTRPGkids as well if anyone wants more info!
