This is a surprisingly fun game. I did encounter an obstacle or two that filled up the entire length of the screen so I didn't know if I had to move it up or down until I started moving it around, which was difficult to manage at high speeds. Not sure if that was intentional to increase the difficulty or not, but it did feel a little unfair. While this game is lacking in presentation, I actually found it to be more engaging than another similar game I played during the Jam called Inversion Flappy Bird (go check it if you haven't already).  This is a cool little game with an idea that could be taken further.
