Shadow Truck Jumps

It's much too hard, you need to have the levels tested by people who never played in order to evaluate the difficulty correctly, this is frustrating and not fun.

Starting right from the bat with a level filled with pit isn't a good idea.
Put first some flatter levels, with ramps but no pit, to let the player get used to the jumps and physics, then introduce the pitfall little by little.

The game has potential, but since it's too hard, most people will give up without even passing the first level.

Damn it took me nearly half hour to beat that first level

Edit: If you decide to keep the difficulty as it is (even if I really advise against that), then remove the life bar. You can't have such impossible obstacle and a life bar on top. It's incredibly frustrating to pass a difficult obstacle only to die right after because of damage.

Once again, I see what you wanted to do with this, but it wasn't very well executed.

The game has a walkthrough which itself gets one star on the first level. I find this hilarious, further watching the walkthrough demonstrates nonsensical approaches to levels, including amongst other things that you lose a majority of your "hearts" as I will call them, to flip the car over an obstacle. This boggles my mind design-wise, but who knows, maybe this is the norm now. Regardless, the design feels terrible. I regret having spent time playing this.
