The Giant's Causeway is a survival game in which you play as an explorer and must discover as many landmarks as possible without letting your torch go out. The gameplay is based on the concepts of orienteering, where the player must navigate through unfamiliar territory and find control points along the way. The environment is inspired by The Giant's Causeway in Ireland, and is procedurally generated so that it is different and unpredictable each time the game is played.
