Interesting demo, thank you! The art style is top quality! The game has potential.
However the story is not related to the theme of the jam: "harvest", which is required. From the game itself "a parasite that feeds on your fear" <== this is not harvesting, but leeching. Harvesting is the active gathering of mature crops, resources, or energy for a positive, often sustainable use. Whereas leeching, is the draining of resources—often passively, unethically, or to the detriment of the host or source—giving little or nothing back.
