this game is really boring and all of the obstacles are pretty much the exact same. digging holes, boomerang switches, fans and dash blocks are the only things you will ever come across and by the time your done with the first world you just want the game to end. after the first world though the game reveals to you its shitty progression and forces you to backtrack to get items that you could not have gotten earlier due to not having certain characters. this continues for the rest of the game and it is very boring.
