i've already forgotten which skelly it is cause I'm awful with names, but I'm working on the path puzzle and it won't let me click another piece after the first one?

I'm just being taunted with the flashing red space but it wont let me click another piece to put in. I've tried refreshing the page I've tried leaving the game and going back, nothing seems to be doing it for me. anyone else having this issue? Any way to fix it?
Those circles are blocks, you have to set your pieces around them.

That black piece is a block. You have to go around it. You can hit the check puzzle button to restart.
