You pilot a luminous starfighter and defend Earth against waves of geometric invaders before they breach the defensive line. Each alien shifts horizontally then descends in tight formation, demanding quick reactions and precise shots. Example: clear a column to create a safe path. Caution: letting any invader cross your ship’s y‑axis costs a life instantly.
Behind the neon action runs a lightweight 3D rendering engine that scales to any screen size and operates entirely in your browser. Difficulty buttons adjust invader speed and projectile velocity in real time. Example: switching from Normal to Hard doubles horizontal drift. Caution: rapid toggles during heavy fire may briefly spike frame time on older hardware.
Use this shooter to sharpen hand‑eye coordination during short breaks or offer a nostalgic challenge at events. Example: project the fullscreen view onto a lobby screen for friendly competitions. Caution: reloading the page resets the score and level; finish a round before refreshing. You may switch control mode, yet sudden input changes can disrupt rhythm.
Features:
This rundown covers every control element and enhancement you will encounter.
Dynamic Difficulty Selection
Choose Easy, Normal, or Hard at launch to alter invader drift and bullet speed immediately. Example: Hard increases alien velocity by 50%. Caution: novices may tire quickly.
Precise Mouse Aiming
Move the cursor to steer the ship smoothly toward the pointer, enabling pixel‑perfect shots. Example: sweep across the screen to herd invaders. Caution: high‑DPI mice exaggerate travel.
Keyboard Shortcuts
Use ←, →, Space, P, and F keys for movement, shooting, pausing, and fullscreen. Example: tap P during a call. Caution: holding Space drains focus.
Fullscreen Immersion
Toggle fullscreen to hide browser chrome and maximise play area. Example: press F on projectors for audience impact. Caution: some browsers block fullscreen without user interaction.
Real‑Time Score HUD
Score, lives, and level appear at the top, updating every hit. Example: watch hearts decrease after contact. Caution: HUD vanishes if custom themes override text‑shadow.
3D Particle Effects
Explosions, thruster flicker, and starfield particles add depth without heavy GPU demand. Example: notice sparks after a hit. Caution: disabling WebGL drops effects.
