Ask HN: Feedback on a ClojureScript game engine for functional programmers

So I built a game engine in ClojureScript over the course of several years to scratch a personal itch. I wanted to express 2D web games using a functional and declarative style that supports my love for the fast feedback loop of REPL driven development. After lots of big life changes, development has stalled, but I keep coming back to it as a source of infinite curiosity and creative work. I want to share this here to gather feedback from the community and share some of the ideas that came from building this.

What do you think about the approach I took here [0]? Do the goals of the project (functional, declarative, repl-driven) resonate with you? As an example of what it looks like in real usage you can see the demo app in the repo. A more detailed discussion of the implementation can be seen in a talk I gave at Clojure West [1].
