Knot is the 31st level in Chip's Challenge 1. This is one of the easiest levels seen for a long time in means of layout; however, there are only 29 seconds to play the level. Nevertheless, it's still reasonably easy; try to follow the force floors to speed things up. 29 seconds is only enough for 140 chips, the one step before touching any chips, and the four steps into the exit. With 118 chips to collect, that would leave 6 seconds and a bit more. You will run over the same space twice several times, but this will be made up with the force floors, if the level is done correctly.
Step 2R, then tie the knot by running in streams of URDLDRURURDL 2D LU 2R U. The exit is just to the right.
