In the end, between start and goal there is only a single block. I was the one opening that block, everybody went through, and I was trapped. One arrow, however, stayed behind, tried to help me get out, was stuck with me for some time, and told me to not clear that last block in order to have other people help me out without just going through.
I think you can solve that one with only three cursors, maybe even two. In some levels you don't need to open the last barrier at all. You can just wait in front of it, and if you have opened the other barriers in the right order, they will close in such a way that you are displaced into the goal.

Whoever you are, thanks <3
