Enemy waves hit fast, so every upgrade feels like a split-second instinct. You’re constantly shuffling pieces around, trying to squeeze out just enough power to survive the next push. The field never settles—one sloppy merge and your whole line can collapse in an instant.
The merge system keeps each run unpredictable. Power spikes land at strange, perfect moments, and a clever placement can flip the fight before you even realize what happened. It’s quick, restless tower-defense strategy built on reacting, not rehearsing.
