Smartly written, it overshadows most tower defense titles with its emphasis on character growth and world-building. One can grow attached to Slack, for example, much more easily than one can grow attached to a nameless battlement or turret.

The game provides a range of challenge suited to players of any skill level, with the new game + feature providing plenty of replay value. Highly recommended, even before the developers released a free upgrade.
