It was super unclear what was and wasn't an illusion at times, which would be cool if it weren't for some obvious questions, like: I take it the lava all wasn't real, so did nobody notice that the ground of that Prague square was immediately fixed after Molten Man was defeated?
The drones are blowing shit up to correspond to the Elemental attacks, so it's not like when the hologram stops there's no damage left behind.
