Topic, Level "Circle to Circle", game "Rolling Turtle"

1st circle: You can get through without any jumping. Just climb the right side slowly and roll through.

2nd and 3rd circle: The above method is not possible due to the "messiness". So what you have to do is jump off the left hand side (just below the gap)straight through the hole. But it doesn't require a running start as i think you are doing. Just climb slowly, and you should almost be standing still when you jump. The point at which to jump does not need to be that accurate, but it will prb take a few tries to work out the right sort of region.

When the level starts, you are at the bottom of the first circle, both sides closed. So I roll back a little to get speed. Then I go around once, for the sides to open. Then I am at the bottom again. But I don't stop there, since I need the speed to go up on the left side again, and shortly after the open hole in the left side, just before you lose contact with the circle wall, you have to jump. If you are lucky (heh...) you will make it through the hole on the right side. I get the timing right let's say one out of 25 jumps, the other times I either miss the entrance or hit the black line. Same with circle 2. But with circle three, no chance, it's impossible so far.

this is the left side of the circle jump when you are between the lower part and the middle part... this only works if you stand still at the point

The spot where you have to time the jump on the way up in the circle is so small, if you miss this spot by a micrometer, you are either dead or miss the entrance to the tube. So you need a lot of luck with the timing.
