-```
-pip install .[prompt,vis]

-- `[prompt]`: enables commands autocompletion (available for generated games only). To activate it, use the `--hint` option when running the `tw-play` script, and press TAB-TAB at the prompt.
-- `[vis]`:

-    To activate it, use the `--html-render` option when running the `tw-play` script, 
-    and the current state of the game will be displayed in your browser.

 where `custom` indicates we want to customize the game using the following options: `--world-size` controls the number of rooms in the world, `--nb-objects` controls the number of objects that can be interacted with (excluding doors) and `--quest-length` controls the minimum number of commands that is required to type in order to win the game. Once done, the game `game_1234.ulx` will be saved in the `gen_games/` folder.
