Click down to fly upwards. Don't click down to drop. After you pass the first building, the score will increase by one point and will continue to increase by one point every second. Try to get a good high score! If you touch the buildings or the ground, the game will end.
I made this as a coding challenge for myself. I'm pretty satisfied with it! The only references I used were one for the hitbox used on the car (https://scratch.mit.edu/projects/67727504/) and one for the scrolling background (the project is no longer available), the rest was my own code.
