Shaper is a puzzle solver game in which the player must change their shape to solve each level.
The player has the ability to change their shape between several different shapes with number of available shapes increasing as they progress through the levels. When the player wants to change shape they can select from the options available along the bottom of the screen. These will then show on the current shape where the next shapes lines will occur the player can then time the change to suite their needs. If they wish to change quickly to the next desired shape they can just double click on that shape and they will change straight away.
At the first levels the objective of each level will have a fair bit of leeway in the ability to achieve. This will slowly disappear as the player learns how to time the changes between shapes, to get the desired affect need to solve the level.
