If you just want to experience the game and don't plan to play it in depth, the above default keys can be used to play with your hands crossed. If you want to play it a little more deeply, the default keys are a bit old-fashioned. At this time, you can download the key configuration I have initialized to your computer.

Note: It is best to play with a handle, you can try it.

(Optional) Reinitialize the button configuration

Just follow the screenshots below:

The following figure appears, indicating that the initialization is successful.

I reinitialize the keys:
Keyboard WSAD buttons -> handle up, down, left, and right

Select and enter the game
