One problem I encountered. This ad keeps popping up, and every time it does, I have to close it with my mouse cursor. After doing that, my cursor wont get locked in the game again, so I keep clicking outside of the game.
I have the same issue with the cursor being released by the game when I close an add. For the game to take back control of the cursor I have to click inside a menu (settings menu or the gun shop menu). I’m on Firefox.
