The new art is much more detailed and attractive than the old "art" (which was really just quick "programmer art" sketches). Most of it is even animated! While I don't consider this art to be "final" and I intend to eventually have it replaced by a professional artist, I think it's good enough for (what is currently) a free game. Even so, I welcome your feedback on it if you have any!
Here's a (rather rough) gameplay video featuring the new art:
And a handful of screenshots as well:
