We could add a difficulty level to the game.

Easy

• Shorter songs, and you only increment by 1 note at a time.

Medium

• Longer songs, and you initially increment by 1 note, then increment by 2 notes 1/3 of the way through, and 3 notes 2/3 of the way through.

Hard

• Same as medium, but the cubes no longer flash when the notes are played at the beginning of the round.

NOTE: These are rough ideas for difficulty levels. Please input your ideas and help me refine this.

This is a good issue to work on because we have to support a wide age range: Ages 3 - 6.
