Two breakable blocks
Walls are interactive objects in Seedling.
Walls are square-shaped from the player's perspective. The inside design has sub-squares which have red, blue and black borders. This border pattern flashes outward, alternating in these colours.
First seen in Woshad, walls barricade certain narrow pathways to prevent the young seedling from passing through. They can only be passed through when hit by a Ghost Spear or ghost sword and will block the seedling's path if he leaves the screen which they are in.
Walls are also found at the entrance of Ghethis, preventing the player from getting in the area too early. A Ghost Spear must be obtained first before the player can get into Ghethis.
