I never played the original Paperboy game, but this one definitely sold me on the idea. It could be a great game if a solid remake was made. I really liked the visuals and the variety of graphical settings you included.
I did run into some technical issues though. It seemed like there was a problem with shader compilation or loading, because when the loading finished, the game froze for me. After restarting, the road did not load in at all. On the third try, everything finally worked.
The game also felt pretty difficult. I wish the difficulty settings actually worked because I got knocked down so many times by birds, cars, or sometimes for no clear reason. Still, I would love to play a polished version of this for hours and try to chase a high score. Awesome revisit to a classic concept.
