Nice puzzle, albeit that it is difficult to see what happens inside the structure. Nice first move. I had to use the ToA trick; is that in line with the designed solution?
Not sure what tricks you intended but I used some but not ToA. Wasn't loving the hard to see areas but they were not hidden and therefore I was able to achieve the win. Thanks
@Meko Guy Might have been a low ceiling, Spoiler the central slider is used repeatedly to open/close passages and push B to where he can continue.
@Jom - There's a hidden draggable close to B EDIT - Too bad some authors have to do that - I don't know why?
Pretty nice level, was wondering how to get started, but while messing around, I finally got where the draggable was located. After that things were easier. Thanks.
