I definitely had to play the windows version so I could hear the music. It sounded really good and worked with the the sound effects. The download version also appears to play and control faster/tighter
The visual style was very well done and unique. My constructive feedback on it is that I think it can create some difficulty/ambiguity in determining the location of objects in the distance. Having the grid lines help, but I noticed the barriers were not always lined up with them on the left/right side, which might help when you are going very fast. If there are more improvements in the future, creating simpler versions of objects that are far away that will render better and then swapping them out to the more detailed variant up close might also be something to consider.
For the speed up ability, I enjoyed going as fast as possible, but I felt like it was more punishing to do so as it just made it more likely I would crash. Having something like a ramp that lets you jump obstacles or long pits that can be overcome a high speed jump might be something that could make it feel more rewarding to go faster depending on the routing
Overall, I enjoyed it a lot, and look forward to seeing your future entries
