The game's play is done through a point and click interface. Players must visit various locations within the game's fictional town of Harvest, which can be done via an overhead map. By speaking to various townspeople and clicking on special "hotspots", players can learn information and collect items that progress the game's story and play. Harvester also features a fighting system where players can attack other characters by selecting a weapon and then clicking on the target. Both the target and the player's character have a limited amount of health available, allowing for either the player or the target to die. Players can choose to progress through the game by solving puzzles or by killing one of the non-playable characters.
