What's New

Updated Admob SDK.

App Description

This is a game that repels attacking invaders by inputting Morse code.
If you have just learned Morse code, let's try.
The rate of progress of the invaders that you are attacking becomes progressively faster as the level increases.
When characters are displayed in the entire display area, they are occupied and the game is over.
Invaders with the same character can be repelled at once, and the more characters are repelled at the same time, the higher the score will be.
If you make a mistake, you will be penalized, so be careful not to make a mistake.
With the load button, you can recall the score of the cleared level and continue. The information of the cleared level can be deleted with the clear button.
Now, have fun.

There is a bonus stage, after Level12.
