Endless Labyrinth Description

Endless Labyrinth is a puzzle original to this blog to the best of my knowledge. The object is to draw a single closed loop passing through adjacent cells in the grid. All colored squares and numbered squares are contained in the loop. It must go straight through red cells and turn in any direction at blue cells. The loop must also pass through each of the numbers in order, going from 1 to 2 to 3 all the way up to N and then back to 1, where N is the amount of numbers in the puzzle (5 in the example below). Finally, the grid is toroidal, so the loop may pass through the edge of the grid to the other side at any time (think Pacman). The solution is unique.

Below is an example puzzle and its only solution.
