Atoll

Atoll is a puzzle game, where falling entities are "Eyots", residents of Atoll island. Player's goal is to make rows and columns of like colored Eyots (4-match) in order to drop them to the island. While there is no time limit, each level has a condition of specific number of Eyots to safely drop.

There are 6 colours of Eyots and from time to time, "egg" can be dropped that will after a few turns turn into Eyot of random color. If a column is overloaded with Eyots, putting another one will be the lowest in the column and increase the water level.

Dropping is controlled by the player, either using a mouse (left mouse click) or keyboard (space key). There are 3 difficulty levels and high score systems.
