There's a nice approach to this problem which is described and
implemented in the MonadPrompt package[1]. Basically you have
prompt :: MonadPrompt p m => p a -> m a
which allows you to interact with the outside world. The beauty
here is that the interection is generic, you may write a pure
simulator (like yours), an IO-heavy game (like what you're
trying) and possibly more, like unit tests and property checks.
