Looking for an anime I watched as a kid, it had a shape shifting witch/wizard chasing the "hero" through a castle/maze... At the end someone dies on one of the castle spires

Sounds like you've spliced
Two of the Unico movies together,.

Unico In the Island of Magic

The evil puppet wizard Lord Kuruku and his giant
Toy dragon chase Unico and his friend Cherri
Around his maze-like fortress

The Fantastic Adventures of Unico

Baron de Ghost takes a tumble off his mansion's tower
And is impaled on a castle spire

Thank you, that's it... I guess there was a reason that unico got blocked out of my memory and all I could remember was the bad guys... kind of girly. That as well as robot carnival were always on before the adventures of mark twain [claymation] on whatever station it was.
