Double click the flag to start and restart. You are the player controlling the sliding water treatment plant. You will try to catch these raindrops before they hit the ground to symbolize the water that gets polluted through CSOs. There are three game modes, each progressively harder than the previous one with more trash and faster rain. Every now and then power-ups and bonuses will pop up on the screen, such as the star that makes you bigger, the lightning that makes you faster, the sun that slows down the rain, and the heart which gives you another life. Beware the trash though, as if you hit it you the rain goes a lot faster. The goal is to last as long as possible without losing all of your lives and to set the high score, which I achieved at 470 on drizzle.
