The look of this is stunning — the vase turning while Prometheus stays put is a lovely idea, and the black-figure art sells it completely.
One thing that stopped me cold on the first vessel: there are two fires with the same icon and the same "SPACE" label, and only one of them does anything. I went to the wrong one first, held Space, nothing happened, and assumed the game was broken. I'm guessing the other fire is where you deliver the flame — if so, hiding that prompt until you're actually carrying fire would have saved me a few confused minutes.
Smaller one: Show/Hide on the side panel works, but I'd have liked Hide to go further — the vase is the star, and it could take up a lot more of the screen when the panel is away.
