Started working on the prototype.
Implemented a simple lobby system and a basic gameplay loop.
Working on the multiplayer is a bit of a head scratcher. But I'm getting into it.
"Smart Join" is trying to establish the connection to each of my friends zerotier IPs and then connects to whoever responds, there might be a better way, but that will do.
I'm still not sure about the 4th player, having a guide on how to solve the level doesn't seem fun.
Maybe I should drop the idea and make the 4th player a "game designer" and let them adjust different variables like player speed.
