Hours and Hours and Hours of fun. It's amazing to see what the community can do with the tools provided, and the game allows you to create pretty robust levels built around the best platforming physics of all time. I love this series, and that nintendo has passed off the reigns to the fans to create the levels they want, and find myself going back to this game constantly. I do wish some of the search features/online ui was better, but Nintendo is bad at making online user friendly. it would be so easy to fix!
