Falling Meteor

All falling meteorites in the game will be randomly generated from the left and right sides at random times. After landing, they will rebound in place. After hitting the boundaries on the left and right sides, they will also rebound in the opposite direction. There are four levels of meteorite size. Large meteorites are destroyed. Afterwards, it will split into two small meteorites at the upper position of the original place. The initial health value of the two small meteorites is half of that of the large meteorite. The smallest meteorite will disappear completely after being destroyed and will no longer split. The color of the meteorite corresponds to its health value. Meteorites with greater health value are usually darker in color. Meteorites with the largest health value are red, and meteorites with the smallest health value are green. The color of the meteorite is constantly changing as it is hit, and the overall performance is a process from dark to light. Brown meteorites are a special type of meteorite that gradually increase in size as they are hit by bullets. After its final explosion, 4 props with different functions will be produced (one randomly generated each time). The first type of prop is a gold coin prop, which will directly earn a certain number of gold coins after being picked up; the second is a freezing prop, after being picked up, all the meteorites stop moving and the sky starts to snow; the third is a bullet prop, which has the effect of a main gun When firing, in addition to firing normal bullets, it will also fire two beams of oblique bullets; the fourth type is a small follower, which will generate a small cannon around the main gun and fire along with the main gun. The validity time of the latter three is 15 seconds. During the game, you must avoid being hit by any kind of meteorite. The small cannon will disappear immediately after being hit by the meteorite. If the main cannon is hit, the game will fail. Pay attention to target selection when firing. When facing multiple meteorites at the same time, reducing the number of meteorites as quickly as possible is the most effective way to eliminate the threat. The effect of using oblique bullets is rare. It can attack meteorites while avoiding facing danger head-on.
