Unfortunately, I'm not sure a game as small as asteroids would

multiple developers would just step on each other's toes.

The problem you're having doesn't have anything to do with file
reads. Every time you call (take 5 data), you're calling it on the
same item 'data'; your variable 'data' doesn't change between each
call. The chief thing you have to understand about Clojure is that
variables never change. Never.
