Lovely game, nice sense of speed as well as polish!
One thing that I noticed is that some actions are done with both left and right, something that is impossible to do on a controller (joystick/dpad).
There I would rather have a button to start the game or to activate boost!
Also I would love to see some smaller gaps over time, I was reaching over 10000 m, 104 x combo and it felt like I only lost because I lost a bit of a focus, not because it became more challenging over time.
Just some small comments on a really good game!
