What if there was an event that spawned a bot-clone of yourself on a named brick.
And the bot would mimic your actions but in reverse.
Every step you took, every animation you made, the bot would do it too.
This would make it possible to make
mirrors
Just imagine a bathroom with a mirrored part on the other side of the mirror.
When the player almost enters the room, he could step on a brick to spawn a clone of himself in the mirror room.
It would feel exactly like a mirror!
And when the player leaves the room, the bot could be killed (silently) by walking on a brick behind the spawn brick.
I think this is the way other games do it too.
