Update v1.1.2

I have updated the game to v1.1.2. - Improved the Jet Exhaust model. - Optimized the explosion effects for better performance. - Added creaking sound effects while the player's hands and feet are moving. - Updated the tower model to make the ground boundaries clearer. - Implemented a complete pause of the game during the pause menu (local mode only). - Changed the language settings to be saved in the save file. - Fixed an issue where the target values for side missions on the level clear screen were not updating in multiplayer mode.
