You must prevent the ball from leaving the room. Glass walls are built on three sides of the room, the lower side is empty, you can build a glass wall at the bottom by clicking the screen or mouse button. Pay attention, this wall appears for a moment, so choose the right time so as not to lose the ball. The ball bounces around the room, and when it approaches the bottom part of the room, you need to block it. Keep in mind, the game is getting harder and harder - the longer the ball stays in the room, the faster it moves. |
