Về demo này

In Demo mode the player tries a few stages of the game.

The intro stage is exactly as in the full game. The player using the computer keyboard or a MIDI piano keyboard can play piano watching the notes on the staff.

After that, even if the player has selected different difficulty level, the first stage with just two music notes begins.

Then the player is able to play the first four stages normally, adding one note at a time like the full game, before reaching the first music theory papyrus and finally returning to the intro stage again. 

All the sounds and music are functionable.

A game that expands in real life.
