Merge Creature Attack

Instructions:

Merge items by dragging and dropping them and aim using the mouse cursor

Hold off on merging every low-tier weapon the instant it drops; sometimes it pays to stockpile a few matching pieces so you can jump straight to a stronger tier instead of wasting drag motions on duplicates.
Watch which enemy types are approaching before committing your merged arrows toward a single lane, since later waves mix armored and fast-moving creatures that each respond differently to raw damage versus rapid fire.
Keep an open slot near your strongest merged bow at all times, because a cluttered board makes it much harder to react quickly once a tougher wave starts closing in from multiple directions.
Prioritize combining bows over lower-impact items early on, since a handful of upgraded bows tend to clear a stubborn wave faster than a wide spread of weaker, unmerged weapons ever could.

Drag any two matching weapons together and drop one on top of the other to merge them into a stronger version.
Move your mouse cursor across the battlefield to aim your active weapons at incoming creatures in real time.
Click and hold briefly over a cluster of similar items to line up several merges back to back without losing your place.
Release the dragged weapon only once it hovers directly over its match, since dropping it a fraction off target can cancel the merge entirely.

A straightforward merging system turns basic arrows and bows into genuinely more powerful gear without any complicated menus getting in the way.
The fully rendered 3D creatures give every wave a distinct silhouette, making it far easier to judge which enemy needs a heavier weapon and which one you can safely ignore for a moment.
Combat rewards quick thinking just as much as raw firepower, since the smartest players are constantly matching, merging, and repositioning rather than sitting still.
Each enemy type carries its own traits and quirks, so no two waves ever call for the exact same defensive setup or weapon combination.
