What is Islets Defense?

You defend a mist-covered kingdom in this single-player, turn-based tower defense game. Across fifteen stages, you explore hidden tiles, build a village, feed towers, and upgrade them with wood and stone to repel slimes. Each turn uses one of four action cards; the rightmost card has a stronger effect, and your chosen card then moves to the leftmost position.

For you if...

+you enjoy balancing resource production with careful building placement
+you like replaying stages to improve your score

Not for you if...

−you prefer real-time combat over deliberate, puzzle-like build orders
