The way that those games achieve it is by placing a SurfaceGui that is “attached” to the camera, and then drawing the part in front of it (closer to the camera) so that it appears on top.
You can also just make that part of the gui transparent so that you can see the part.
I can’t make the part transparent due to me having a background image followed by that one frame instance ontop of the background 
Just a few tips about the tutorial section.
They shouldn’t be really long, but they shouldn’t be super short either. Trying to convey a simple idea which is super hard to do is great. This probably belongs in development discussions as kind of a “PRO TIP” type of thing.
Go more in-depth about what it is you’re doing, and why it’s awesome if it’s not immediately obvious. I can’t see what’s awesome here, and I’m a little confused as to what the tutorial does.
I think a pretty neat idea for a tutorial would be like 5-6 cool UI tricks such as how to create shadow on your text which isn’t very hard to do, but a lot of people don’t do it simply because they haven’t thought of how to do it.
Um… I don’t think this deserves a tutorial. This effect is extremely simple, and if you don’t mind me saying it isn’t very appealing. A fade effect or a button shrink/grow would seem more appealing to me
