When I saw that it's only 63kb, Itough it's gonna be a simple and boring game, but in a way, it's nice.
Great game! Simple yet challanging. All it needs for 5 stars is some good ambient music.
Other possible improvements are more levels and being able to create my own curves.
Interesting game idea, but not really fun to play.
Possibly allowing a lot less accuracy and less time would spice it up ?
The idea is good. Proficient flash artists should do well on this.
It's not really "relaxing" without relaxing music, though. Add some appropriate music and you'll be much better off. :)
The concept is defiantly interesting. Maybe make the black curve thicker, or the red one thinner. It requires a bit too much perfection to be fun.
