Unite Drop is a simple yet deep 3D falling puzzle game where you drop colorful balls and merge them together.

* How to Play
Just tap the screen to drop balls. When balls of the same color touch, they merge and evolve into larger balls. Keep creating bigger and bigger balls. When you merge the largest purple balls, they disappear.

* FAQ
Q. Is there no online ranking?
A. It's planned for future updates.

Q. Is there no sound?
A. Sound effects will be added in the future. BGM is undecided.

Q. A ball disappeared even though it wasn't the maximum size
A. When 3 or more balls of the same color stick together at exactly the same time, they may disappear. It's a bug, but we're keeping it because it's interesting.

Q. Red balls bounce abnormally
A. Small balls bounce greatly when hitting large balls, but if they then hit another large ball, they can bounce so much they fly out of the box.
