The last of three senses, the sense of smell, is perhaps most associated with dogs, as the most important way of perceiving the world. Therefore, it plays a significant role in our game.
First of all, sense of smell allows you to check from a distance, whether the substance sprayed in the air is safe. The red gas is toxic and will hurt Bea, while the green gas will relax her. Smells also affect other creatures - for example, communicating with a creature stressed out by toxic fumes may not go well. Some gases can change their properties temporarily - so it's worth checking them regularly with the sense of smell before approaching them.
Bea's sensitive sense of smell also creates scent paths, leading to important objects in the game world. The red, negative paths will lead you to destructable toxin tanks. Green-blue paths will show the way to hidden collectibles. Neutral smells will indicate other interactive objects, such as a Drydon spear left on the ground, which Bea can pick up and use. The yellow scent paths lead to story objectives important to Bea - such as the smell of a teddy bear that Bea follows on Gula.
Also, remember that Bea has her own scent that her surroundings can react to! Bea can change her smell by bathing in mud, to confuse other smell receptors. Pay attention to the color of the particles near smell receptors, to see what scent the sensor will react to.
See you in the next post where we will talk about the inhabitant of the planet Gula, with a nose that is almost as sensitive as Bea's.
