Thank you for this great experience! I haven't read any of the other comments, but I have a couple of constructive points:
- It would be great if the 'bridge' (meaning the line the notes reach and must be played) could be closer to the key labels, to make it a little easier to keep your eyes on both!
- I love the way the music keeps rolling, but I would really like to have to 'master' the instrument before I'm able to move on. For example, you should be able to hit all the notes three times in a row before it's 'collected'.
But otherwise a fantastic game, well done!
