Hayfever

Hayfever is a platform game about Thomas, a proud young mailman with severe allergies. You guide him through a dangerous world to collect his lost letters, using the effects of different allergens to turn his allergies into tools for traversal.

Allergy-powered movement

Pollen lets Thomas build up a sneeze that propels him through the air, while smog makes him swell like a balloon. Peanuts have a different effect. The allergens change how he interacts with the world, and the game’s movement mechanics are driven by sneezing.

Worlds and levels

The game has four worlds, each based on one of the year’s seasons, and 140 challenging levels. There are 240 collectibles, and the game may also contain a secret world.
