- Added BMP_1_EXPLOSION_DOWN.png to original and preview directories. - Added BMP_1_EXPLOSION_LEFT.png to original and preview directories. - Added BMP_1_EXPLOSION_RIGHT.png to original and preview directories. - Added BMP_1_EXPLOSION_UP.png to original and preview directories. These assets are part of the explosion animation for the game, enhancing visual effects during gameplay.
