Horochi's Challenge

Horochi's Challenge is a single-player 3D puzzle game that combines pushing crystal orbs with changing gravity. Guide the orbs to their goals, connect the power circuits, and bring the computers to life.

Six directions of gravity. Every move matters.

Look around each stage, then choose which of its six faces should become the floor. Change gravity and watch orbs and characters fall toward their new footing.

Push an orb first, or change gravity first? The order of your actions can send the same pieces to very different places.

50 stages across five worlds

Explore grasslands, forests, a town, a castle, and a demon castle, each with its own voxel scenery. Learn to use fixed floating blocks, rail platforms that slide along a single axis, and pillars that move with gravity.

Start with simple orb-pushing puzzles, then tackle larger rooms and more intricate combinations of mechanisms. Highlights show which mechanisms respond to your selected gravity direction, helping you plan what will move and what will stay in place.

Two characters to position, one player in control

Bimba joins Meguru from stage 21. Switch between them and decide who needs to move and who should stay put.

Gravity affects both characters, including the one you are not controlling. Plan where each will land before you turn the room.

Find a solution, then earn the gold medal

A stage's minimum move count is revealed after your first clear. Solve it your own way, then return to see how many moves you can save.

Match the theoretical minimum to earn a gold medal. A perfect solution on your first attempt counts, too. Collect medals on all 50 stages to unlock a special reward from Horochi.

PC controls and room to experiment

• Move with WASD or the arrow keys. Drag the mouse to look around and use the wheel to zoom.
  
• Choose a gravity direction with the globe UI or keys 1–6, then confirm the change.
  
• Undo a move or reset the stage to try a different idea.
  
• Learn the rules through Meguru and Bimba's short skits and live 3D demonstrations.
  
• Japanese and English text and voice clips, two music tracks, and adjustable sound, graphics, and language settings.
