The concept is nice but it gets out of hand pretty fast. I can see how the insane speed boost might fit the theme, but ultimately it makes the game kind of unfair because I can't possibly use my skill to avoid obstacles along the way. The only way to win is to play over and over again until I memorize where everything is and when I need to jump. Also, I'm wondering if the game really is supposed to speed up super fast in a short amount of time or if this is due to my framerate being high. You'll want to make sure things such as speed increase over time are calculated in FixedUpdate or multiplied by Time.deltaTime so that it's framerate dependent
