Needs work.

After 12 lives on easy difficulty, I finally conquered the first hill, having found that if you go too fast you hit the back of your truck on the ground, and going too slow flips your truck. upon doing so, I found that there was several deadly drops just out of sight, which I lost another life to. From there, I lost another 2 on the hill before finally completing the tutorial level. From there, it was gravy till level 5 where you leave no indication of how to deal with the giant ice cubes that come your way.

Dude, I don't know if this is news to you, but the tutorial level is supposed to be the EASIEST level, NOT the HARDEST. From your description, there were no ice cubes in the first game, and it would probably be appreciated by many to learn how to deal with them. The physics are OK once you get used to them. there also was the issue of the tread between the tires COMING OFF after a drop in level 3.

Fix it up quite a bit if you are planning on releasing a third one, otherwise, fix this one to be a bit more enjoyable.

Not to sound harsh...

...but if vehicles in real life were this under-powered and performed this poorly, there'd be some really pissed off customers and a lot of unemployed mechanical engineers.

same as others

just doesnt work right

What Azagg said.

There's some really weird gravity going on there.

broken?

All I can ask is if this is broken. The physics seem so wonky and the truck controls so poorly I couldn't make it over the first hill in 10 lives. Either the tracks would bunch up and flip me over on the shallow dips or the truck would bounce and flip on the deep ones. There seems to be no room for skill, you just have to hope you are lucky enough to not fall over...
