Hi Stuart, There is a bug in end-game? which means it never ends. I'm not sure if this is the most idiomatic way to fix it but it seems to work.
< (defn end-game? [{:keys [apple snake]}]
< (cond
< (lose? snake) (do (reset-game) "You lose!")
< (win? snake) (do (reset-game) "You win!")))
---
> (defn end-game? [game]
> (let [{:keys [apple snake]} game]
> (cond
> (lose? @snake) (do (reset-game game) "You lose!")
> (win? @snake) (do (reset-game game) "You win!"))))
Cheers
Tom
(I include a version which won't run off the edge, enjoy)
