Hi Nick,
Your background sprites are so fun! Shooting the bikers was quite difficult at first until I got the hang of it. Then it became extremely easy as their movement is quite predictable. It felt like I wasn't moving forward all that much and the trees felt impossible to avoid at times. The trees felt like they were spawning and flying right to me as opposed to moving through a forest. That said the game was still enjoyable and I commend the overall look and feel.
