I like the game, it is funnny.

Some things that I miss it is some particles for the car like smoke, when you hit something some sparks, and etc.
Also about the sounds I like the engine and hit sound, but I would like to hear a different hit sound if I am invulnerable like a shield hit.

Good job! ^^

@quemagalletas Thanks for the feedback! I agree with everything you said. The truth is I am new to Unity and never did (and don't know how to do) particle systems in Unity. It's definitely something I want to learn very soon.

Some scrolling scenery would have help to improve the speed feeling. Dont need a lot of work here basic cubes would have been enough.
