So, I've tested all demos. The entires I lik most are a7itude, bulldozer, knightsonwheels and take it easy.

#4 Bulldozer
It's a nice game idea. I like this kind of mini games very much. But there is something special missing. But I can't tell what.

#3 Take It Easy
Nice idea to script take it easy as watchable game. The programming is done great, but the game itself is too boring for watching.

#2 Knights On Wheels
I like this game very much, especially the big canyon-like racing track. But the steering in curves are a bit annoying. The vehicle turns too slow.

#1 a7itude
Very nice game idea. It's well coded and the graphics are also very nice. I had very much fun with this game.

So my vote goes to a7itude
