The characters feel true to the show. They could have used more voice lines. the game's difficulty is pretty much based on how much you grind and break stuff so you can power up everyone. I wish you could choose other people to play as. the battles are fun and will have you using all your characters. bmo is arguably the mvp because of his ability that refills your ability points. I wish that we could have different ultimate abilities to choose from even if just 2.More powers for each character and more characters to select from, would be awesome.. The missions are fun and you explore the islands enough but it could use secrets and more collectibles.
When you have to rescue the candy people and penguins its probably a good idea to write down how many you've spotted, rescued and left behind, and where you found them because you can have too many on the boat at once and have to leave them there. When attempting to get the trophy it can be difficult recalling where they were before and you will waste time backtracking to find them. don't make the same mistake I did, it got frustrating searching all the islands for the last ones.
I however have not returned since getting the platinum trophy. and that makes me sad because it was fun while it lasted. That is the biggest problem with this game, it's just not long enough. and needs more characters and enemies.
