Your instruments are lying to you. Not all of them, not all the time, but enough that you can't tell which. 

 You're driving a rover across a crater basin at night, searching for a relay station from a wrecked predecessor's last known fix. Your only view of the world is built from what your sensors claim: odometer, compass, and radar. 

One of them might be frozen. One might be reporting where you were a few moves ago. One might drift a little further off with every turn. They won't tell you which. You'll have to catch them contradicting each other. Trust the wrong reading and you'll drive confidently in the wrong direction. Trust nothing and you'll never move. Find the relay, get within lock range, and transmit, before your battery runs out!

Features:

• Procedurally seeded runs: share a seed, compare routes
• Three difficulty tiers, each stacking more (and sneakier) sensor lies
• No tutorial hand-holding beyond what the post-it notes tell you (and even those might be wrong)

Comment your seed and score, others can try to beat it!
