How to implement the classic game Bubble Hall in Java

##Main design

• Design the game interface and use swing to implement

• Draw the game Start interface, end interface, map, protagonist, props

• Realize bubble explosion

• Realize dual protagonist PK (points system)

• Realize prop drops and corresponding attribute bonuses

• Realize game sound effects and background music
