You need to register to play, but you just need to supply a name, email and password.
There will be a new stage every day (except fot january 8th, as it is a rest day in the Dakar). There are 14 stages in total.
Enjoy.
A lot of fun to drive and high speed through the sand! Really gave you a sense of speed.
The vegetation wasn’t being occluded by the truck however. Was very noticeable having a bush sticking out the top of the vehicle.
Nicely done!
Wow. great job. Did you use wheel colliders?
New english version available:
Another Ikiman classic!
wow… cool… what kind of script car do you use? 
I’m just releasing the game to client and making last minute adjustments. So little time to reply.
Anyway,
Yes I found wheel colliders a great choice and even after two years I’m learning how to manage it.

The car script is one of my own, here you can download a tutorial with a basic version of it:

Use the script as you want, it is an old version made in Unity 2.X (includes the complete project and setup), but it works just updating to 3.0.
Enjoy.
Thanks for the car tutorial for physics, also great job on the game!
Nice but you get lost too easily 
The game is out, I edited the original post with the correct links.
Happy New Year to all.
Congrats on your new release. Looks very nice and polished. Playback was too slow with everything on highest quality to react to steering properly, but I wanted to see how nice everything was at their highest settings. One thing I noticed was that when the screen faded to black, the needles on the instruments were still white / visible. I’m seeing this on my MacBook Pro with x1600 graphics running Firefox.
