Good concept executed well, and I was surprised by the amount of songs in the game. Normally, the biggest problem with jam rhythm games are the charts desyncing with the music. In this regard, I think LoveLine actually succeeds pretty well. However, I think where the game does falter a bit is the charting. Not because it's off, but because it's cluttered. The sections that have rapid uses of the same notes or alternate between different notes for 20 in a row are often hard to read, which makes it difficult to get rhythm down. Because of that, I generally liked the easier tracks.
