Does it though? I thought this was a web-native engine written for WebGL/JS or wasm. But it's just an n+1th Unity project that got exported to the browser. There are (tens of) thousands like this on itch/Steam/mobile app store.
With tools like Unity you can focus more on the actual game development instead of building the tools for the game and then risk never releasing the game.
Using an existing engine with an existing network library is not technically noteworthy.
The resulting game might be fun, polished, worth playing etc., but from a technology side, it's not interesting.
