TIP: Only one shot at a time — make it count. Shields crumble pixel by pixel.

11 × 5 alien formation marches sideways, drops when hitting edge. Speed doubles as they thin.
Bottom 2 rows = 10 pts, middle 2 = 20 pts, top = 30 pts. UFO = 100–300 bonus.
4 shields absorb fire but deteriorate block by block.
Game over when invaders reach your base line or lives hit 0.
Clear a wave to advance — invaders start lower and faster.

Desktop: Mouse drag on canvas to steer, click to fire. Hold arrows for smooth move.

Mobile: Hold ◀ ▶ to slide. Tap ● FIRE. Drag finger on game to move.

Touch drag = move ship Tap game = fire

Last shot counts. Let enemies bunch below shields to funnel their fire — then pick off edges to slow descent.

Shoot UFO for random 100/150/200/300 when you hear its hum.
Aliens shoot from lowest alive in each column — clear columns to control their fire lanes.
