There are a lot of things really great about this game - mainly the concept of collecting trash which is a good idea to play around with when it comes to gaming.
Though there were a heap-load of upgrades and a hell of a lot of area's to play through which are both very impressive - it felt like the levels themselves were quite repetitive and not very fun in the long run. Levels didn't have much rhyme or reason to them either. While I LOVED how one controlled the truck - both the control scheme itself and the amount of control one had on the truck from flipping over to standing on-top of the deflector - all that trash falling from the sky and the random rockets appearing didn't really do much for the gaming experience. Putting aside that non of it seemed to make any real sort of sense - the game just didn't really give you much to do except drive and deflect rockets. Garbage falling was so abundant one doesn't really pay attention to it - just drive through it and rack up the points. That's a shame since the car control scheme is so great, easy and fun to use. The levels didn't really let you use that control scheme to it's full potential.
Music was good and fitting though somewhat repetitive after awhile.
All in all I believe you have a potential gaming GEM in your hands, all you have to do is polish it well so it's full potential will shine thorough.
I'd also love to see a car design option to play around with for your truck, color, pattern etc.
So thanks for the game and good luck in the future!
