Space Invaders gameplay: invader grid, shields and cannon

WHAT YOU GET

1978, FAITHFULLY 11×5 invader grid, 2-frame animations, accelerating block movement, and the original one-shot-on-screen rule. Waves start lower each level.

DESTRUCTIBLE SHIELDS 4 bunkers eroded shot by shot — and chewed through by descending invaders.

8-BIT SOUNDS Every effect is a code-generated square wave: pew, boom, UFO siren, and the four-note bass march. Press M for silence.

CRT LOOK Scanlines, phosphor green and gel-overlay tints, hand-made 5×7 bitmap font. Big crisp pixels, zero blur.

MYSTERY UFO Crosses the top with its warbling siren. 50? 100? 300? One way to find out.

NATIVE & SAFE Swift + SpriteKit. Developer ID signed, Apple-notarized, automatic updates via Sparkle. Hi-score saved between sessions.
