Really cool use of red-figure pottery style! My wife was an art history minor, so seeing unique styles brought is always a plus in my book.
Audio cues were definitely essential. And quite fitting for each animal (though I couldn't hear the hydra).
I'll agree with HalfSmore that it felt like a lot of keybindings. Though I don't really have a suggest of how to better that at the moment. Will do some thinking and let you know if anything comes to mind.
Really solid entry all around. I think you nailed the aesthetic both visually and audibly. Great job.
