How to play & scoring
Type a word’s next untyped letter to lock on. Finish it to destroy the enemy. Backspace releases the lock without losing progress. Matching targets are chosen nearest to the defense line first.
Every five completed words builds your multiplier, up to ×5. Mistakes, escaped enemies, and pulses reset it. Armor awards ×2 base points; each carrier stage awards ×3.
Space uses a pulse: ordinary enemies are cleared without points, carriers are stunned for three seconds. One pulse recharges every third sector, up to three. Practice starts with three pulses but does not recharge them.
Overall WPM = correct characters ÷ 5 ÷ elapsed minutes, including waits for enemies to appear. Engaged WPM uses only the time actually spent typing, ignoring gaps while you wait for the next word. Pauses are excluded; speeds appear after five seconds.
Scores and progress are stored only in this browser. Arcade records are separated by difficulty, word pack, and character options. Sprint has fixed rules. Practice has no score leaderboard.
