The big highlight for me here is definitely the art! The scene of a little doggy running through the hills and jumping over bumps in the road is pretty cute. I also think it's clever to have a green highlight around the area where all the obstacles are, to ensure that they stand out from the background. The gameplay, while simple, feels pretty engaging. I initially felt that the random spawning of objects could be unfair, but after learning that you can hold the jump button to jump as soon as you hit the ground (I instinctively assumed you had to let go of the space-bar and press it again for each jump), it did get easier. My only real complaint is that the music is a bit loud, but aside from that, your choice is sounds is good!
