Hey, I kept playing this several times! It's a score chaser for sure. I enjoyed taking the shortcut down the middle and evading the car.
Some things can be improved like the bike's pathing. I don't know if you intentionally made it possible to move sideways in the road. It would be good if you let the bike be locked to the middle of the path, like in the game Pac-Man. Right now it's too easy to get stuck on the corners.
I would suggest adding a beep every second when it gets to 10 seconds and under, and a happy "ding!" when you deliver a package.
