"Ball Streams" is an engaging and challenging game where your objective is to prevent balls from falling into a tank. As the player, you must strategically move the lid of the tank to block the incoming balls and keep them from reaching the bottom.

The game features a visually appealing environment with a tank positioned at the center of the screen. Colorful balls descend from above, aiming to find their way into the tank. It's your task to swiftly react and manipulate the lid's movement to intercept the balls and divert their trajectory.

To control the lid, you can use intuitive touch controls or keyboard inputs, depending on the platform you're playing on. As balls descend at varying speeds and angles, you need to employ quick reflexes and precise timing to position the lid in the path of each ball. Successful interceptions will cause the balls to bounce off the lid, preventing them from reaching the tank's bottom.

The game progressively increases in difficulty as you successfully block more balls. You'll encounter power-ups, additional obstacles, and faster ball descents, which add to the excitement and challenge. Power-ups might include temporary speed boosts for the lid, larger or smaller balls, or even temporary barriers to aid your interception efforts.
