Flatten is a puzzle game. Players need to change between the 3D dimension and 2D dimension to clear the level. When you are in the 3D dimension, you can jump over one space; when you are in the 2D dimention, you cannot jump but can move ignoring the heights. There are some Runestones in the level. If you put them on Runes, Hidden blocks will appear or the layer might rotate.
