Armel is a 2D mini puzzle platformer game where the character has been reduced is in a music sheet world and is living composed music. Avoid various obstacles to reach to the music notes that help you move forward by building the next music lines of the world. The character runs, jumps and can push a rock to get the puzzle right and move to end a level. Armel was sent in exile by the evil queen on his world because he refused to play for her as he was the best musician. For this, she threw a curse on him and sent him to go and make compositions before he returns.
