Ancient Islands is a hardcore tower defense game developed for Nintendo Switch and released in 2022. Players defend a village against waves of enemies while simultaneously managing a small settlement economy — constructing resource-gathering buildings like woodcutter's huts, building a marketplace to trade materials, and developing magic schools to generate mana and unlock spells. A deep skill tree offers branching specializations, from archery and gold production to resource gathering and melee combat, with each branch unlocking new structures and towers. The game features a resource trading system that lets players convert surpluses into scarce materials, and individual tower targeting rules configurable across 14 enemy traits — allowing, for instance, mage towers to prioritize low-health flying enemies while archers focus on fast, magic-resistant foes. Additional systems include blacksmith equipment upgrades, troop formations, multiple difficulty levels, and building synergies that reward careful placement planning.
Exchange resources to get the ones you need. You want to build a specific tower and you lack wood while sleeping on the stone and gold? - no problem! (if you're willing to pay the price). The map you're on is rich in one supply while lacking the presence of others? - Trade! You're not a mage type? - Turn your mana into gold! 
Develop your abilities in a way you like, there are tons of available combinations, you can specialize yourself in getting gold and archery, woodcutting, and melee fighters, or go full resource gathering. The choice is yours. Each branch of the skill tree has new buildings and towers ready to be unlocked!
