Neat game. I also had the resolution issue btw (1440p screen). Music was cool - very stressful.
I did notice that the obstacles seemed to be spawning in at a time rate rather than a distance rate, so if you slowed down you'd get a whole bunch of obstacles grouped up, making them even harder to avoid. Dunno if this was a deliberate choice, but I found it made it most effective to just hold up the whole time.
I really liked the little opening cutscene - very funny! Good job :)
