Synchrony is a puzzle game involving time-travel.
And an alien.
With three legs.

As the protagonist, you have to travel backwards in time and work with past (and future) versions of your self in order to solve each level.

In each level, your objective is to reach the red flag.
You're given a fixed number of time capsules that allow you to go back in time to the beginning of the level, where you can see all your past selves in action.

You will have to work together with your past selves and manipulate objects in the level like switches and platforms in order to reach your goal.

Each level is progressively more difficult and introduces new concepts to be used. The levels also have additional milestones to be achieved that require a greater degree of planning, thought and skill.
Your ability to achieve these milestones determines your rating in each level.
