Puzzlerium Tour: Go Square

Solution video for today's puzzle as well as for the Slitherlink should be out soon. Next on the series is a region division puzzle that is a hybrid between two Nikoli puzzles, which will then be followed by an engrossing Tapa.

Rules: Draw a single loop that has an orthogonal path and visits all cells exactly once each. Numbers indicate how many 2x2 squares in the corresponding outlined region have all of their four cells visited in immediate succession to each other. 

About Go Square: Go Square is due to Anurag Sahay, and debuts with the puzzle published in this post.
