Casual mini-game -- Wash the pigeon

Here's another casual game with a fresh style. In the game, you need to control the rainmaker to perform artificial rain, turning black pigeons into white ones. Be careful not to touch any pigeons of any color. If one rainfall cleans multiple pigeons, there will be a combo bonus. Cleaning a flying red ball will make it invincible.

Gameplay: Use the mouse to control the movement of the rainmaker and click the left button of the mouse to make it rain.
