A road winds across a meadow to your castle, and everything walking along it carries a word. Type the word and your archers loose a volley at it. Let it through and your gate takes the hit.
Each wave sends a column of enemies up the road from the edge of the woods. Every one has a word floating over its head. Type the first letter of any word to target that enemy, and every correct letter after that sends an arrow arcing over from the gate towers. Finish the word and a full volley takes it down. The enemy closest to the gate is always the one to worry about, so its label starts pulsing red as it gets near.
A wrong letter is marked in red and breaks your streak, but you keep your target and can carry on. Esc or Backspace drops the target if you want to switch.
Kills earn gold, and holding a wave earns a bonus. Between waves there is a short build phase where three stone pads beside the road light up, each with a word and a price. Type the word to build. Fire towers throw a firepot whenever you kill something, burning letters off the next enemy in line. Frost towers chill the ground around the gate so everything on the last stretch slows down. Volley towers fire at a second enemy after your words, knocking off shields or finishing small fry. Each tower has three levels, and the gate itself can be mended for a growing price.
You do not have to wait out the build timer. Press Enter to start the next wave straight away, and every second you skip is paid back in gold.
On Advanced the words are a letter longer, enemies move about a fifth faster, you start with less gold and a typo lets your target lurch forward. Waves get longer and denser either way, so every run ends when the gate falls. Most runs last two to four minutes.
No. An enemy is hit the moment you type the last letter of its word. Space is ignored, so you can type word after word without stopping.
Your first letter targets the one closest to the gate. Enemies on screen at the same time usually start with different letters, so this rarely matters.
Every word you finish scores ten points a letter, multiplied by your clean streak, plus a bonus for each kill. Holding a wave adds fifty points per wave number, and a hundred more if nothing touched the gate.
