v1.04: First update request

Preface:

• On the first day of the game's release, we received our first player update request;

• A player reported that when playing other games in fullscreen mode, they couldn't see the current computer clock in real time;

• Therefore, a feature was needed to switch this game's display to the "clock" display;

Update contents:

1. Implemented the clock display feature; you can click the button to switch to showing the current time;

2. Added two buttons that appear when moving the mouse over the game panel - one toggles the clock display, and the other opens the main panel;
