Thanks for playing and glad you liked it! Yeah, the artist really knocked it out of the park with the UI design! He's done many projects and jams before (check his Itch page). I've also done quite a few before, including a few commercial indie projects, and the winning entry to this jam last year (Snake Eyes), which uses the same base engine as this one, which I've been working on for a while. Having a working engine going into a jam like this is pretty key to being able to focus on what's important.
The other two are new to game jams (I think this was their first jam, but don't quote me on that =).
