thanks for playing and thanks for your feedback! we might continue development for a couple months, to make it a little more full featured / polished, so the suggestions are super helpful! we used unity netcode and UGS for the lobby / relay/ transport. there are starting to be some good tutorials online for unity netcode. i can personally recommend the free videos from taro dev and samyam on youtube. one of the other team members took the unity netcode code monkey course
