Galaxy Guard

A squadron of pixel aliens is marching down toward the planet. Slide your laser cannon along the ground and shoot them all before they land. Each time the formation hits the edge of the screen it drops one row closer — and the fewer aliens are left, the faster they march.

Controls

• Keyboard: ← → or A / D to move, Space or ↑ to fire. P/Esc pauses.
• Mouse / touch: press and hold on the game — the cannon slides under your finger and fires automatically. On phones you can also use the ◀ ▶ and fire buttons below.

Rules

• Only one of your shots can be in the air at a time, so aim carefully.
• The four green shields block shots from both sides and slowly crumble. Aliens touching them eat through.
• A mystery saucer sometimes crosses the top of the screen — hit it for 50 to 300 bonus points.
• You have 3 lives; you earn an extra one at 1500 points. If the aliens reach the ground the game ends.

Scoring

Bottom-row Bloblets are 10 points, middle Clawbots 20, top-row Zappers 30. Each new level starts the squadron a little lower.
