A crystal will not stay on its button
In the narrated demo, the Wizard’s swap puts the crystal where the Wizard was standing. Begin the swap from the button you want occupied. Simply aiming toward a crystal does not determine a useful landing square for it.
The central crystal blocks your plan
For the demo Wizard room described as having a central crystal and side crystals, the demonstrator handles the middle crystal first. This advice applies to that narrated layout; it is not a rule that the centre must always be solved first.
The first Warrior–Wizard pair cannot leave
The recorded first pairing is solved by getting the two heroes into line of sight and swapping their sides. Each can then use the exit that the other could not. Compare your room to that situation before applying the idea.
