What is the Koch method?
You keep a practical character speed from day one and expand only the symbol set, so you never learn to depend on slow code.
How does the next level unlock?
A new character unlocks only once you hit the target accuracy. Sent and entered text are compared so confusion patterns stay visible.
Can I revisit earlier stages?
Return to any unlocked set to strengthen weak symbols, with progress and settings resets kept separate.
