Move with WASD or arrow keys, fire automatically (or hold space depending on version) to shoot. Press shift to focus-fire (slows your ship for precise shots), and Z to deploy a screen-clearing bomb (limited supply). On mobile, drag to move and the ship fires automatically.
Survive each level and defeat the boss to advance.
Your Hitbox is Tiny - The ship's visible sprite is much larger than its actual collision area; what looks like a hit often misses by enough to count.
Move in Sweeping Arcs - Constant small movements are better than jerky direction changes; smooth motion is easier to course-correct than stop-and-start. Focus Fire for Bosses - The slowed movement during focus mode makes boss-phase precision dodging far more reliable.
Save Bombs for Real Emergencies - The screen-clear is your panic button; don't waste it on regular waves you can dodge through. Learn Boss Patterns Through Practice - The first attempt at each boss is reconnaissance; the second is when you actually try to win.
