Merge TD by Instant Games Studio

Merge colored units strategically to create stronger defenders and clear waves of enemies in a dynamic tower defense setting. Combine units by dragging them onto each other to unlock higher-tier versions while managing limited space on the battlefield. The challenge increases as enemy types diversify and waves become tougher, testing your merging efficiency and placement skills.
