Love the art style. That's minimalism done well right here!
This game just hit me just right. All the elements fit together perfectly to form this bite-sized chunk of pure atmosphere. It looks great and sounds perfect. I'm willing to bet this will be in top 5 for graphics and sound categories.
The gameplay is not complicated, but I think it doesn't need to be in a game like this. Using two buttons to pedal works really well. For the two minutes I played this I was completely engrossed.
I often say that polished 5 minute jam game is better than unpolished 15 minute game. I think you took this even further. Great job!
