What time is it? It is time to pay homage to The Legend of Zelda and A Link to the Past with Little Orbit and Way Forward's Adventure Time: The Secret of the Nameless Kingdom. Finn and Jake, along with a cast of more than a few recognizable characters from the hit cartoon, bring you an adventure that brings a modern spin on the look and sounds very close to Link's quests from the days of the Nintendo Entertainment System. Temple dungeons, hidden stairs under bushes, fetch quests, bombing open caves and angering wizards with said bombs are all things this game references from The Legend of Zelda and the audio choices brought back a nice memory of playing the NES back in the day. Adventure Time: The Secret of the Nameless Kingdom also brings the fresh humour and quirkiness that the show is known for and a story that will task our heroes to save the kingdom without a name before they make it worse than it already is.
Step 1
Play through the game looking out for the Gum Globe, Piles of Wood and Thump Shard collectibles. All other collectibles will be needed to progress through the story, whether to open up new areas or gain access into one of the four temples Finn and Jake must fight through to free the Princess sisters on their coronation day.
Below is a map of the area with all the important character locations shown.

The Red Throne has been ruled as missable due to the possibility of missing the collectibles following all boss fights. Please consult the guide for full details if you wish to keep the playthroughs at the minimum.
Please also give Marceline's Closet a read before you upgrade Jake's shield in the swamp, just so you don't miss your chance the first time around as this trophy has also been reported as missable in certain regions.
Look out for the five places Gunter is hiding (see The Real You). It is also best to work on fully upgrading Finn's sword and armor (see Blade of Grass and the location of the Like Like Sweater information in the Be More trophy descriptions respectively) as well as getting at least two of the three endings (See A Good Idea At the Time...) before moving on to your second playthrough.
This will net you all but two or three of the trophies. By the end of your first run, you should have finished all collectibles and received the following trophies:
Princess Day
Rattleballs
A Penny Burned
The Party's Over
Why Did You Do That?
Wake Up
Food Chain
Level 99
Stanley Grayble
Love Games
A Day in the Life of a Bun

Step 2
Play through the game again, preferably on a second save file, without collecting any extra Thumps, upgrading Finn's sword, the armor upgrade or The Like Like Sweater. This run will mostly be for achieving the final trophy Ambitreacherous and the platinum, but you could also save one of the three endings for this run. After a quick romp through the four temples and the various areas of the Nameless Kingdom, you will achieve the final three trophies:
Ambitreacherous
A Good Idea at the Time...
Billy's Bucket List
