Causality is a puzzle game about manipulating time, altering the sequence of events and changing the outcome of each level. Set across strange and alien landscapes, help a group of stranded astronauts find a route to safety. Travel through time, work with your past selves and solve paradoxes as you take on this uniquely challenging puzzler. Each level represents a brief but hazardous moment in time. Levels are completed by guiding each astronaut to an exit that matches their colour, within a limited time frame. When all astronauts reach an exit the level is complete.
