I wonder how maintainable this is even for clojure experts? Simple feature - add 'jump' control. How long would it take you?
It looks quite familiar, it generates a plain data structure and reacts on a set of user inputs. I‘d have to look up how this communicates with threejs (which is done via a wrapper library) and what the semantics of that is, but otherwise the code looks clean and simple to me.

Same here, it's very concise, love it.
Looks pretty amenable to hacking with the boy.
I know we're using an engine, but still shocking how little code it is.
