Kingdom Rush/YMMV

• Breather Level: The Ruins of Acaroth is rather easy compared to the other bonus levels in the game. It's not a walk in the park, however...you do have forest trolls to deal with.
• Goddamned Bats: Unfortunately, the nature of the game that these easily slain, frequently encountered foes actually ARE a threat, as they can come in a Zerg Rush that your towers may have a bit of difficulty handling.
  • If you are doing Iron Challenges, Wargs will cause hair loss. Since you only have 1 Health, Warg's are easily able to slip past your defences for an easy win.
