Game Planet Protector

Blast alien waves before they crack your planet's shields in this fast arcade defense.

My first run ended in about forty seconds. The little blue drones aren't a problem, but then the orange ones start curving, and suddenly your mouse hand is doing panicked figure-eights. Game Planet Protector drops you right into orbit with a single job: keep the planet's shield from hitting zero. You move a crosshair around the screen, click to fire, and watch the debris pile up. Every wave adds a new trick – ships that split, ships that shoot back, a big tanky one that just absorbs bullets like it's rude. The mouse-only control is tighter than you'd expect. There's a slight cooldown on your cannon, so you can't just hold the button and sweep. You end up learning to lead the fast movers, snap to the edge of the screen where spawns come from, and save your screen-clearing bomb for when three waves overlap. I kept wasting the bomb on wave 2 out of panic – don't do that. The scoring is old-school arcade: chain kills without missing for a multiplier, and you'll see why the leaderboard exists. Nothing here reinvents the wheel, but that's exactly what makes it work. It's pure reaction-time fun without twenty menus of upgrades. If you like twin-stick shooters but only have a mouse, this scratches the same itch. The art is bright enough to see everything at a glance, and the hitboxes are fair – when I died, it was my fault. You'll lose a good forty minutes before noticing. For a free browser arcade game, Planet Protector nails the loop: spawn, shoot, dodge, repeat, but with enough enemy variety to keep your brain from going idle.

Use mouse to play.

Watch the edges of the screen, not the planet – spawns start on the left and right. Don't hold down fire. Tapping keeps your accuracy tighter and avoids wasted cooldowns. Save your bomb for wave 5 when the splitters show up in pairs. Chain kills without letting go to build the score multiplier. If your mouse feels too twitchy, lower your DPI before blaming the game. Focus the orange curvers first; they're the ones who'll chip your shield when you blink.
