This is a super funny and creative idea that made me laugh a lot.
Level 6 drove me a bit crazy, because of the complex labyrinth. Sometimes I stopped on a cross-walk and pedestrians walked slowy into my car and died immediately. On the one hand it was funny especially in combination with the sound and the cool ragdoll. On the other hand it was a bit annoying because I immediately lost and had to restart.
I was also a bit irritaded by the slogan. "One Button GTA" would for me be: you could just drive over the pedrestians and go really rampage. In the game I had to strictly follow the real traffic rules. Consider breaking those and create some funny moments with that.
But anyway: Good job you did here, and totally fits the theme.
Here's the link to my game if you would like to play it as well. It's a turn based strategy game
