It'd be worth your time before you get too deep. The two issues that I ran into:
* CORS issues -- deploying on some sites (esp. gitlab and github pages) runs into issues because of shared buffer requests.
* Assuming you get past the CORS issues, there is still extremely slow load on OSX Chrome -- the app eventually loads, but holy smokes it takes forever.
Both of those nearly made me give up on Godot, but I'm very happy to stay with 3.5.x until those get resolved.
