About
Islets Defense is a turn-based tower defense game in which you build a small village to gather resources and defend your castle. Carefully plan your actions, as each move brings the enemy waves closer! Strategize building placements and play your cards wisely, as timing and order are key.
Islets Defense is a turn-based tower defense game focused on resource management in which you build a small and efficient village to support your towers and secure victory.
A turn consists of executing one of the four available actions, each with its own unique functionality. The order of the cards plays a key role, with the rightmost card offering a stronger effect. After completing your turn, the chosen card moves to the leftmost position, pushing the others one step forward. Consistent and efficient use of all four cards is key to building a solid defense.
Allocate your towers in strategic positions, sustain them with food, upgrade them with wood and stone, and ensure a strong defense against the slimes. Chests and stage modifiers will offer new strategic opportunities, with unique towers and various upgrades to explore.
Each building has different upgrade options for you to choose from. Build the most efficient village by making smart decisions that synergize with your positioning strategy!
The mist has covered your entire kingdom! You start the game with an unexplored map, ready to be revealed! Use the exploration action to reach new resources, gain visibility for your attack towers, and discover hidden treasures!
Advance through stages, complete challenges, and earn diamonds and feathers to unlock and face different biomes! Islets Defense is the game for those looking for a classic tower defense experience mixed with the chilling vibes of a resource management game, all wrapped up in easy-to-understand mechanics filled with creative possibilities.
