Honestly, it is a shame this game ended up the way it did. It has so much potential to be one of the best 2D Mario platformers ever made, and in some ways it is. However, it ultimately flops in so many aspects. No collision in co-op takes away all of the fun from stealing your friends moves, jumping on your friends to access new areas, throwing each-other for the sake of griefing, and so forth. The wonder flower was a great idea that was held back by repetitiveness by its endgame with its quirkiness and the boss battles were god awful. Some of the worst I have seen in a AAA title in a long time. Extremely easy, boring and lacked creativity. The animations itself are gorgeous and I hope this game acts as a stepping stool for upcoming mario titles. I look forward to the future.
