Crossings synchronizes two intersecting game world loops. The first is a racing loop with an SUV that winds through a countryside track. The second exists in the same world but reflects the perspective of the wildlife. Deer populations cycle within the adjacent forest. The first game seeks to achieve a good race time, the second game has a slower pacing. At various “deer crossings” the game worlds meet, sometimes with tragic consequences. In these cases, animal populations are modified by race times.
