update

This update updates some scene models and art resources,
Added some background sound effects.
Since things have been busy recently, it can't be completed in a month to find the reset problem. After all, the development progress of one person is slow. Although I'm very interested, I wish I could break myself into two people. Therefore, under the condition of ensuring the quality, the game is updated in "two weeks". That is to compress the updates every two weeks into one release, which can greatly improve the efficiency. Thank you again for your support.
