1. Added tutorial level
Due to the complexity of the game system, it is not intuitive for novices to communicate the system design. We have created tutorial level. If you play for the first time, you will automatically enter the teaching levels at the beginning. Otherwise, you can select "Tutorial" from the main menu to enter.
2. Fixed the issue of price detection when purchasing a single item.
3. Adjusted the value of some remote skills.
4. Adjust the volume of background music in some scenes to be invalid.
