Fun game, took a few tries to get to the end... but the blue car exploded right when I made it - it still displayed the win screen though, so I'm counting it!
The controls took some getting used to, reminded me of some old dos games, but wasn't too bad after a while, I think it might be a little better with precise shot direction control using the mouse (like gungeon or similar) considering it seemed like your shots do a lot more damage to the blue car than the zombies do. That's an interesting balance decision, but I feel there's some philosophy behind it.
Took a bit to realize how to restart - since the gameplay only used the keyboard (and both hands), using the mouse felt a little out of place for any type of interaction. Could use a game over screen when the blue car explodes also.
I think the biggest thing is that the car doesn't really head to a destination, it just kinda meanders through the city for a bit until you reach the end of the map (or maybe it's time based?), so I didn't really get a sense of where I was heading or why. Not saying it needs a deep backstory or anything, just the sense that the player is making progress :)
Little things aside, this is great work for such short time!
