📖 How to play
① Sort
Split them into “know” and “don’t know”
Swipe each word card left or right.
Getting it wrong is fine — the words you put in “don’t know” are the ones
that show up in the battle next.
② Battle
Pick the right meaning out of four
Tap the answer that matches the monster falling from the top.
A wrong tap costs a heart. Running out of hearts is not the end — you get
review cards, then you go straight back to where you were.
③ Speaking
Tap first, then say it out loud
Tap the mic button and it turns 🔴.
Say the word after it turns 🔴 — the other way round and nothing is listening yet.
Nothing is judging your pronunciation, so say it as loud as you like.
④ Chapters
Beat the boss to open the next one
One chapter = 20 stages + mid-bosses + a final boss.
Beating the final boss opens the next chapter. You can also go back to a
finished chapter any time from “Settings → Choose chapter”.
⑤ Battling others
“Password Room” is how you meet a friend
Whoever types the same password gets matched together.
It is not a secret code you have to know — you and your friend just pick
the same word.
No one around? Practise against a villager instead.
