So, I can build all the rooms, but nothing happens when I build the throne room. I run out of my original rooms, and nothing happens. No rebuy, no heroes. Maybe it's broken on Brave?
It might be Brave yeah. im using an experimental branch of Godot for web to C# builds, so I wouldn't be suprised if there are compatibility issues with certain browsers.
Id try downloading the PC build and see if you run into the same issue
