This game looks really nice and is a cool concept! I think that the repetetiveness of the QTEs did start to get old pretty quickly, and it would be nice to have more feedback on how I was doing (immediate positive or negative sound for each key, and then a rating of how I did at the end). I also think it would be good to reduce the time in between keys, as it was a bit boring just waiting for the next one to appear. Still quite fun and I played all the way through!
