Some members may ask for license sooner or later so you can also add that in your post as a positive.
You can find the licenses in the bottom footer of website.
I know and I've seen it before I made that comment. My point is some members may rely only on the information provided in the main post. You know the usual asking before searching.
I opened the site and was greeted with a "not available in your jurisdiction" pop up but good thing I can still view the home page. You said Metamask integration will come soon so I'm curious how will you implement the country restriction once it is live?
I believe will have the same system as regular register blocked for the restricted country, once they're registered with metamask they will get a notification from restricted country and can't play on the site.
I would wait for their official response regarding this matter.
Using a VPN from allowed countries while accessing the site through Metamask would be a practice to avoid account resstriction.
