How to approach level 2? 'Play Song' seems not to work, even if the keys are in correct order.

However, this is a great listening exercise and would love to try more complex songs... Keep developing :)

In general i like the idea of a piano which has to get fixed, however as someone with no musical ear this goal is hard to accomplish. 

I have no idea what i'm doing, randomly clicking sometimes lets the cricle go away...

Cool idea, but I don't really know what I'm doing :( 

Cool game :) But I had to look up Europahymne, I think it would be cool if you had a chance to listen to the songs.

Sehr originelle Idee! Cool das das klappt, auch wenn man sich sehr wenig mit Musik auskennt die Lieder nachzubauen.

Hab dumm lange gebraucht rauszufinden, dass ich die Keys nach unten legen muss damit das abspielt - aber top cooles kleines Jam-Game!

Awesome idea, as a piano player I totally love it! The first two songs I knew, at the third I was lost. Would be perhaps helpful to mark the beginning and ending tones in a different color, or add some help tooltips. Other than that it's really cool, a little bit of polishing and maybe more art and that would be a nice game also for non-musicians.
