Rage games are really hard to give feedback for, since so much of what I would suggest probably goes against the spirit of a rage game. What's for certain though is this game has a TON of personality. I love all the pixel art and hand drawn text. Two languages is a really great as well. I'm unfamiliar with the game you were trying to remake, but I assume the classic level is supposed to be the original level design. That seems like a fantastic way to prototype before making your own.
The one thing I would suggest is to look into including sounds! Sound effects are the most bang for your buck you'll ever get when it comes to game feel. Having a sound when you die, or a sound effect for traffic while the cars are moving would go a long way!
Awesome job!
