1.0.24A Changelog - Story, Save slots and Hostile Enemies

This patch adds two major game systems; support for storyline cutscenes and abilities for enemies to attack your towers. The story content will be very light, but give some kind of context to the player.

Enemies being able to attack and destroy the player's towers is a game changer. Destroyed towers will leave behind an unpassable pile of rubble, so enemies won't be able to shortcut through the maze, but will significantly reduce the player's power. Since towers now have health and armor I have a much larger space in which to design enemies, upgrades and items.
