I love the graphics for this game, truly beautiful. The small details are there, like the balloons in the background, love it. I love the mechanics, but I feel the road was a little crowded with cones and holes, but you made the hitboxes pretty well that I can squeeze past them.
My suggestion would be to add some effect letting the player know they hit an obstacle.
I'm excited to see what other features you guys might add. For example, the dog chasing the biker as mentioned in class. I'm also curious about how you're going to implement the currency system, what to buy with it, and such. I also think there should be other events that happen in the game, like maybe if you throw a paper near the sidewalk, an NPC comes out of the house to throw the paper at you. Great job!
