Fun once I got used to the controls! I think it might have been more intuitive to introduce one of the side paths before the opposite path, especially with the way the controls were explained. My thought process went from the first level "The controls listed up and down as teleport, but they don't seem to do anything" to the second "Teleport moves me to the other track, but when I try to move there it teleports me back. Is this a bug?" and it wasn't until the third level that I realized it was tube controls with a "skip 180 degrees" option. Having bottom+right or left for level 2 would have made that smoother. I even think that just forcing you to use teleport for the levels with only two opposite lanes would have helped, if three of the directions didn't end up all behaving as teleport I would have been more likely to try the 4th direction and realize controls were just inverted.
