Vexis

Vexis is a puzzle game where the object is to maneuver a white block through a field into the goal. However, the block cannot be controlled directly -- the player is only able to rotate the field 90 degrees to either the left or right. When the field is rotated, anything not stationary will fall straight down. The player must manipulate the design of the stage, including blocks that disappear at certain intervals and blocks that only fall after a countdown, in order to solve each puzzle. There are several dozen stages included.
