Feature request

Is your feature request related to a problem? Please describe.

It's confusing that you can't really play solo in the browser. The screen doesn't give much hints about this, while Kahoot has a "Play Solo" option

Then the game starts even without any players and you can't click on an answer and start wondering if their some issue in the game or in your browser.

Describe the solution you'd like

Below "Start Game" it's good to explain how the hosting works. Maybe rename the button to "Host live"

Describe alternatives you've considered

It will be great to actually implement the "Play Solo" option.
