|Completed all of the world 5-EX platinum medals without using a guide at all.|
The 5-EX version of the Dedede battle was almost just as easy as the normal one... the Secret Path Dedede battle is the only one that's still hard now, and I think it's the only thing keeping me from getting the last platinum and 100% completing the game. You just have to be really careful while fighting him and only inhale and attack when it's safe, but the fact that it takes 10 minutes to get back there and try again makes it nerve-wracking and that probably makes me more likely to make mistakes.
I like this game a lot... getting the platinum medals makes it more of a puzzle game where you have to figure out the exact strategy to get the highest possible combos, and anything less than the most perfect strat will not be enough. The execution of the strategy is very easy once you know what to do, and you can even take some risky shortcuts in some cases to get a better time.
