How to Play Pocket Zaurus: Juu Ouken no Nazo
Quick start
Press SELECT on the title, select the mode, and press START. Until you get used to it, you may want to choose the slightly easier "Dad Mode". On Dinosaur Island, move left and right, check A Jump, and B boomerang, and use Up + B on the enemies above. There are also enemies inside the item container, so take a look before approaching. Be sure to write down the codes you obtained by defeating the commander, and prepare for input after defeating the boss. I also want to open the crossword in the manual.
Controls
On the ground, you can move left and right, and go up and down the ladder. A: Jump, down + A: Jump down. B: Boomerang, Up + B: Throw up, Down + B: Use the flash you have. In the time capsule, move by direction, press A to bomb, press B to punch capsule. START: Start/pause and display inventory, press again to resume. SELECT: Select mode by title. In the sudden pocket quiz, choose the answer with A/B.
Pocket Zaurus: Juu Ouken no Nazo — About this game
In ``Pocket Zaurus: The Mystery of the Ten King Swords,'' players travel to Dinosaur Island, Egypt, and a futuristic city, aiming to defeat the Space-Time Emperor Salamander and return to their original state. The action on the ground uses boomerangs and jumps, and the battle in the time capsule uses bombs and punches, and the role of the controls changes depending on the scene. If you take the super shield, you can wear a power suit and strengthen it, but there may be enemies lurking in the Botranodon with items. The key to progress is the code you get from the commander, which you enter after defeating the boss to collect crossword clues. I want to record information during the process of assembling the five-colored swords, and check the puzzles in the manual as I proceed.
