Added some useful features.

● The horde interval parameter has been changed to use "days" as the unit, allowing you to set how many days pass between each horde attack (at night). Also, opening the map will now display a countdown timer until the next horde.

● When storage boxes or workbenches are destroyed or collapse, the items inside will drop to the ground.

● When both your backpack and belt are full, picked-up items will drop to the ground.

● Added an option to disable screen shake.

● Added a Discord button to the main menu.

● Added a version number label to the main menu.

● The maximum character level has been increased to 200. As a balance adjustment, some zombie levels have been increased.

● Fixed a bug where, after destroying a skyscraper, it would reappear upon reloading the game.

● Fixed a bug where, after a workbench collapsed, placing a new identical workbench would incorrectly contain the items that were stored in the collapsed one.

Note: The merchant system is about 75% complete. Patches released during this period may introduce some bugs. If you encounter any issues, please report them immediately on the Steam forums or Discord, and we will reply and fix the issue within 10 hours.
