A snail is chasing you.

If it touches you, you die.

Scenario

Based on the "The Immortal Snail" meme. You accepted a deal to win $10,000,000,000 USD, but in exchange, you will be constantly pursued by a snail that kills you if it touches you. It's extremely intelligent, but otherwise has the physical properties and movement speed of a normal snail.

The snail was supposed to spawn anywhere within a 10 km radius of your current location, but you were unlucky enough to have it spawn just outside your bedroom door. What you do from here is up to you.
