From the README

To allow multiplayer mode play the WebSocket protocol is used, that runs over HTTP for asynchronous communication that can occur concurrently. Since browser can't receive a WebSocket connection, but only initialize one, client to client (P2P) connections is not possibile due to the limitation of the protocol (to solve that problem WebRTC can be used).

Above in the image is illustrated the general architecture of multiplayer game. The client entities (or players) are just browsers with support to WebSockets and WebGL.
