Defender

Can you hold the line against an endless asteroid swarm? Pilot your ship, dodge jagged rocks, and blast everything that drifts toward you.

Defender throws you into a tiny ship in a big dark space full of spinning rocks. Arrow keys move you four directions, but there's no drift or momentum forgiveness—tap left and you're instantly sliding that way. Space bar shoots. The first wave feels almost polite: a couple of slow boulders drifting across the screen. Then the asteroid count climbs and you realize every corner is a death trap. The real skill isn't just mashing space. It's choosing which rock to kill first. Small fast asteroids are the ones that sneak up from behind while you're focused on a big one. I lost count of how many times I chased a slow, high-value boulder into a corner and got blindsided by a quick shard. You can only fire forward, so if something's behind you, you'd better turn around before you become space dust. Keep a loose figure-eight pattern going and you'll survive much longer than if you sit still or make straight-line runs. What kept me coming back is the score chase. Every asteroid you blast adds points, and the pace ramps without mercy. The controls are simple enough to pick up in five seconds, but staying alive past the first minute takes real spatial awareness. It's one of those games where you die, mumble 'one more try,' and suddenly twenty minutes have vanished. Small hitbox, big chaos—that's the whole appeal.

Use the "arrow keys" to move the spaceship around Use the "space bar" to shoot down the asteroids

Keep moving in a loose figure-eight so asteroids can't pin you against an edge.
