Python 171/176. Full code here; authentic code now, might clean later. Thought I was fast today, but you all are simply getting too good at this!

Python 3. 1015/169. Quite the jump for part 2, but not quite enough; thanks z3! Full solution

Python 3. Full solution

Python 3, 100/50. Full code here.

Python3, full code on GitHub

Python, 328/89. Code for both parts

Python3, complex numbers for coordinates, using inf to represent out of bounds.

Python3. Full code. Pretty good excuse for structural pattern matching:

Python3, 33/190 (don't ask me about the part 2 fail). Code on GitHub

Part one went fairly fast, but spent quite some time on getting part two right. I settled on the approach of just iterating over the grid and using a boolean to see if I had to count elements or not. However, I had some issues figuring out when to swap, this post by /u/rogual helped me figure it out. After that I lost quite some time on an error that only occurred with my input, not with the example input. It turned out that my loop (which I take form my p1 solution) didn't include the start node, which caused all sorts of counting issues.
