The operation key is not explained, so when I found it myself, I pressed the ESC key, but the game was aborted and the Pi-Boy did not exit normally.
After checking, even if you press the X button to exit without pressing the ESC key, you cannot exit normally.
I wonder if there is a separate explanation for the action keys.
If so, can I change the working key?
Is it normal to always force shutdown?
For a story game, I wish I had a separate key to store.
