I really love your tutorials, but the game wasn't as good as I had hoped. Controlling the string with the mouse is awkward, especially when trying to make close turns. Getting too close at first can make it impossible to recover from the turn. The music is repetitive and annoying, and I ended up muting it after the first two levels. I like that it's something you don't see too often, but it's too difficult to get anything above 2 stars, and it gets more frustrating than fun.
I will consider getting easier to get white stars
