Star Defender is a browser game built for short, satisfying sessions - it loads instantly, plays with one thumb, and runs on any mid-range phone. The setup is simple: 4 lives, bosses with 45 base HP every third wave. Nothing to install, no account, no waiting.
Drag anywhere to fly - the ship floats above your finger so you can actually see - and the guns fire on their own. Your job is positioning: thread the bullet patterns, collect the shield and homing-missile drops, and survive waves that keep escalating. Here you get 4 lives, bosses with 45 base HP every third wave.
Nothing here needs a tutorial or a wiki. Controls are one gesture, the goal is one sentence, and the difficulty comes from execution rather than homework. That is exactly what a browser game should be.
Endless waves, 4 lives, a boss every third wave.

Keep it if you play in short bursts. It rewards a second attempt far more than a first, and the second attempt costs nothing but the tap.
