Wind Runner

In a world, far in the future, where petrol cars are a distant memory and there's no more lithium left for batteries or whatever, a new form of transportation has emerged. The Wind Runner. You're task in this game is to pilot the Wind Runner around the map, delivering packages to various mailboxes.

Once you're near a mailbox, you'll be prompted to press R to deliver the package

•  A and D control the vehicle orientation
• Q and E control the sail orientation 
• Once you're near a mailbox, you'll be prompted to press R to deliver the package

 Follow the arrows to the mailboxes, the arrow pointing to the closest mailbox is highlighted

You need to position the sail correctly in the wind to move in the direction you want. To go up wind, try zig-zagging. The wind will change direction over time too.
