Simple Morse Code

This is a 'simple method' to learn Morse .It works as this: you hear and type one character at a time. You can go as fast or as slow as you want.

The only thing is: endeavor to type the right character. Take your time, but not err. The game stops if your hit rate goes below 90%, or after a 10-second timeout. (We plan to implement a scoreboard in the future.)
