Some objects, such as spikes, have a facing direction. Press [R] to rotate the direction the object will be placed at.
There are currently two layers in the editor: the back layer and the middle layer. The middle layer is the layer the player moves on, but objects like saws and water pipes in the back layer can still affect the player. Press [L] to toggle between layers in the editor.
