How to Play Binary Land
Quick start
Press SELECT on the title, select the penguin to use as the reference for left and right input, and start. First, move up and down to align the two birds, then spread them left and right to avoid obstacles. As you approach the exit, it will be easier to make the horizontal distance from the two birds to the entrance the same, then move upwards and reach the goal at the same time. Get rid of spider webs with spray as soon as possible.
Controls
SELECT selects Grin or Maron as the operating standard on the title screen, starts with START, and pauses during play. If you press the cross button up or down, the two wings will move in the same direction, and if you press left or right, the selected wing will move in the input direction and the other wing will move in the opposite direction. Both A and B simultaneously fire sprays in the direction they were facing just before.
Binary Land — About this game
``Binary Land'' is an action puzzle game in which you control Grin and Maron, who are trapped in a mirror maze in a magical forest. The two birds move in the same direction up and down and in opposite directions left and right, and they must reach the exit at the top within the time limit. Spider webs can be removed with a spray, and if one is caught, it can be rescued from the other. In the second half, birds that switch positions and fireballs that cannot be defeated appear, requiring decisions that can't be solved with left-right symmetry alone.
