Demons vs. Fairyland is a tower defense game inspired by the popular TDs, Kingdom Rush and Cursed Treasure. Build camps and towers to prevent the inhabitants of Fairyland from taking their kids back. These towers house and summon units that will automatically attack enemies within their range. Towers can only be built near camps that are associated with them. You can upgrade towers individually or upgrade a camp to improve all of its supported towers. To build/upgrade towers and camps, you will need gold, which is earned by killing enemies. You also have a few spells that require mana rather than gold. Gain skill points by completing missions, and use them to unlock permanent upgrades.
