After editing and sharing five levels, I've realized you cannot use the move trigger to move a speed portal. At first I thought it was a bug, so I tried it again in another level, but I got the same results. So then I decided to take a look at the editor guide. Since that didn't help me much, I decided to come to stackexchange.
Can I move the speed portal in a Geometry Dash custom level, and if so, how?
