Misunderstood part 2 at first but I knew it would be a dynamic programming thing simply based on the task itself. This let me eventually clear up my misunderstanding. Had an ugly solution where I always switch between player 1 and 2 based on a toggle, and then saw this beauty so I that clever switching as well.

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.
