How to Play Kero Kero Keroppi no Daibouken
Quick start
Start the game with START, select the maze you want to go to with the cross button on the castle maze selection screen, and enter with A. First, practice going from the start arrow to the exit arrow in the apple maze. The arrow on the floor will only allow you to move in that direction, and you will slip if you ride it, so check where you are going first. For melons, look at the direction of the scaffolding and use movement and jump (A), and for grapes, memorize the sample path and then try A. B is used to help or interrupt the cloud, not to attack, so don't press it unnecessarily. Once you get out of the castle, make a note of the password for the picture.
Controls
Cross button: Select movement, maze, etc. A: Jump in the direction you are facing, enter the maze in the castle, proceed to the challenge from the sample path. B: Call for assistance cloud. Please note that if you don't have a cloud, you will return to the maze selection with the balloon. START: Start the game, take a break during play. SELECT: Switch between Keroppi and Stoppi on the solo maze selection screen. On the password screen, press left and right to change the input position, top and bottom to change the pattern, and press A to confirm.
Kero Kero Keroppi no Daibouken — About this game
``Kerokero Keroppi's Great Adventure'' is a work in which Keroppi goes around a castle with a maze to rescue Kerorine who has been kidnapped. In the apple maze, there are one-way streets and underground passages, in the melon, scaffolding that rotates when you step on it, in the grape, a safe path that is shown at the beginning, and in the lemon, a color-changing floor blocks your path. Even though the movements and jumps are the same, the conditions for advancing each maze are different, so it is important to understand the mechanism first. The soft serve ice cream represents room for action and you must reach the exit before it runs out. There are also detours with the help of clouds and slides that open with hearts, and when you clear the castle you will receive a password for the picture. Unlike the sequel, where you run and defeat enemies, this is a puzzle game where you have to think about the path and conquer it little by little.
