NetRacer for Windows

Unzip anywhere and run NetRacer.exe.

The exe is unsigned, so the first launch shows a SmartScreen box:
click More info, then Run anyway.

The first start asks you to sign in. Pick "Sign in with Google" and your
browser opens the NetRacer sign-in page. Sign in, choose your driver name,
which is permanent, and the game signs itself in. The link is also copied
to your clipboard, so you can paste it into a browser yourself if none
opened.

NetRacer is played online. The campaign's tracks are not in this download:
each one is fetched from netracer.alex-wilkinson.ca the first time you play
it, which takes a few seconds, and stays in data\maps\campaign afterwards.

Every finished run is sent to the NetRacer server, which drives your inputs
again on its own copy of the car and the track. A run counts only if it
finishes exactly the way your game said it did. Your campaign progress, your
settings and the replays the records keep live on your account, so they
follow you to another computer.
