After watching the Completionist's review of the single player in Splatoon( https://www.youtube.com/watch?v=FOZVAMHC7PQ), I learned that there are different types of levels. On the poll it'll tell you, but what's your favorite? I like the Octoling levels, Octostriker levels, and the Boss Kettles. Fighting the Octolings is really fun, going through multiplayer stages with enemies and the Octostriker constanly raining Inkstrikes on you until you beat him on his UFO is very enjoyable to me, and Boss Kettles because bosses are cool.
