well, on bottom of the right side of the construct UI you see couple of tabs: Project, Animator and Layers. Click Layers.
You wil propably see one Layer.
Click that little "File iconwith green triangle" then ensure it is on the top (by clicking on the gray upward triangle icon).
Then click and hold the sprites and other HUD related elements and drag then "On to" the layer you recently created (literaly - on it) and drop it. From now on the elements you draged will be assigned to be on that layer (you can always do the same with anything and any layer).
Then click that layer and on the left prosperities tab look for "Scroll Rate X" and "Scroll Rate Y" and set both to 0%.
and you are preety much done
