Monday Mutant 29: Double Entry

Draw a single loop that connects the grid cells. The loop may only travel horizontally or vertically, and never diagonally (so all turns are of 90 degrees). The loop may only turn at the centers of grid cells, and may not cross itself or branch off. Every grid cell must be used, and the loop must enter and exit every region of the grid exactly twice. (The regions are colored as an aesthetic only.)

Nice. Pretty simple, but that's probably okay since I've probably saturated anyone's thirst for challenging puzzles of this kind.

True, though your puzzles of this type were usually easier then you expected.

mellowmelon: I've got a 10x18 puzzle lined up for later today, so be on the lookout. :)

There are four puzzles I was specifically referring to in my first comment: 95, the triple back, the marathon, and the minefield. Words like "brutal" are the norm from people giving feedback on them. Admittedly I did overestimate some others I posted though.

Looking forward to your larger one; I've been wanting to see someone else's take on this type for a very long time.
