Some fonts are blocked on https://www.dominion.games/private-beta/
They are blocked because of mixed content. You can not use http:// javascripts on https:// page.
See attached screenshot
Google Chrome Version 55.0.2883.75 (64-bit)
old Linux Mint
EDIT: I have uploaded screenshot for https://www.dominion.games/ instead of https://www.dominion.games/private-beta/ But the issue is same on both.
There is an icon in the address bar for that.
