Nothing here hehehehehe
So basically, as I originally suggested, to have a successful rickroll your victim(s) have/has to be unsuspecting, which requires having a blank backdrop and sprite unless you want a sprite there. Now, the problem you had which made the backdrop you had keep appearing was you had the "next costume" block on, making the sprite keep coming up. It's a very small mistake easily looked over but can be fixed w/ a few small minutes of coding. If you look inside I actually coded and put in each of the sprites individually, which may be tedious, but makes the project look better. In the end, a few more minutes going over bugs/mistakes is better because it will look better in the end! Good life lesson to have right there, although when did this turn into a life lesson? NEVER. Btw another thing is to make the title "Untitled-*whichever untitled project this is, whether it's untitled-5 or untitled-56*" As that will make it more unsuspecting.
