Trying to find an old game..

Hello. I have been wondering if anyone remembers a game where you play as a colored line that constantly moves in a circular motion on pegs or something, and you can move from one spot to another on the pegs. Also as you move on, the levels get harder (I think there's red lines that move in circles that kill you if you touch them?)

I couldn't find a picture of this game, but I drew this to help: (the black line being the player)



Does anyone know what game this is that I'm talking about? Any help would be greatly appreciated.

Yes, that's it! Thanks to you both for the help
