About this game

This is a new kind of learning app that visualizes Morse code in a tree structure.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Morse Code "Visualized" in a Tree
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Short dots (・) go to the right, long dashes (-) go to the left.

You can grasp the tree structure at a glance, where characters appear at each branch.

By "understanding the structure" rather than "memorizing," you will naturally learn the code.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

• English (European Morse Code, ITU Standard)
• Japanese (Japanese Syllabary, Japanese Morse Code)

Authentic Paddle Operation
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
The paddle UI, split into left and right screens, recreates a feel close to actual telegraph operation.

• Beginner Mode (5 wpm): Single keyer, learn slowly and carefully.
• Intermediate Mode (12 wpm): Single keyer, practical speed.
• Advanced Mode (25 wpm): Squeeze keyer, authentic operation using both paddles alternately.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Practical Practice in Story Mode
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Learn by actually typing practice texts prepared for each language.
The cursor guides you to the next character, and correctness is provided in real time.
The number of mistakes is also recorded, so you can feel your improvement.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
