Barricade

You control a small paddle or block at the bottom of the screen. Your only job is to catch the bombs as they fall. Each bomb you catch turns into a brick, and you use these bricks to build a wall, a barricade, right there in the center of the playfield. The goal is to construct this wall high enough to reach the top of the screen before the bombs can get past you and drain your lives. It starts calmly, but the bombs fall faster as you progress, forcing you to split your attention between catching new ones and carefully placing your bricks. The difficulty comes from that constant multitasking; one missed bomb or poorly placed brick can set you back. It feels like a quiet, focused race against a clock you can't see.
