How to Play MAER Heaven - Boukyaku no Klavier
Quick start
Start the story, read the first destination and inspect the available ARM equipment. Try one displayed touch action in the first battle, observe its effect and adjust the equipped selection before a harder encounter.
Controls
Use the DS field controls and touch-screen menus shown in the opening instructions. Select an equipped ARM and perform its displayed touch action rather than repeating one gesture for every item. Confirm equipment changes and read the next story marker before moving on.
MAER Heaven - Boukyaku no Klavier — About this game
Boukyaku no Klavier sends Ginta and his companions into an original MÄR adventure centered on the mysterious Klavier and the Ghost Chess threat. Magic ARM items turn the DS touch screen into part of battle: different items ask for different actions, so selecting equipment and executing its input both matter. Explore the three-dimensional field, follow conversations and prepare a useful selection before the next fight. Begin by reading the first destination and testing a single ARM's action rather than changing everything at once. This is an adventure with magical combat, and the title's Klavier does not make it a piano or rhythm game. Begin with the opening instructions and practice the main interaction before pursuing optional rewards. Read the current objective, make one deliberate choice and watch its effect before repeating it. A short first session makes it easier to separate a missed instruction from a difficult challenge. Return to the available menu when you need to check progress or adjust your approach, then continue from the next clear objective.
