However, other viruses can end your run if they collide with you. This game offers simple controls and endless fun for players of all ages, making it a great choice for quick play sessions.

How to Play

Players use mouse or touch controls to move their microbe around the playing field. The goal is to guide your nose to touch harmful viruses to neutralize them and score points.

Strategy and quick reflexes are key to surviving and becoming the microbe with the biggest nose.

Keep an eye on your surroundings and use quick directional changes to evade threats. Practice regularly to improve your reflexes and decision-making.
