Beginner Treatment Check

I hadn't played this game before, so I tried installing it the other day. The smooth movements of Hatsune Miku were really great 3D technology. They give you a guaranteed 4-star gacha ticket (is that the highest rarity?) right at the start, which is motivating. One thing I found inconvenient was that the note speed was too slow at first. I think even for beginners, 6 might be tough, so I'd be happy if you could set the standard speed a bit faster. However, since you can change this to your preference, I guess it's fine.
