Not bad, but it seemed like the upgrades were kind of broken: You seem to have to unlock level 4 or 5 on most of them before they really become effective and even maxed, there don't seem to be enough cars. But on the whole, it was decent.
The meters don't stop where you click them. They have a tendency to keep going or jump a bit after clicked, many times taking the line out of the green zone. The angle meter is the worst. The height meter needs some fine tuning, too. In some launch games, the player has some control over flight, though limited. I didn't notice any control and you didn't mention it, so I assume all the control is in the meters. Fine tune those and this will be a better game.
It's similar to Toss The Turtle but I like it.
