Hello! Thanks for trying and providing feedback. I'm sorry you couldn't understand it, however your assumption is spot on. The challenge is to be not just fast, but at the right speed level to avoid overshooting the next platform. Some scenarios also are designed so being at a certain speed level offers a different path to the end. Akin to classic Sonic games, but without the jump button.
I included a Help button on the menu describing the aspects of the game and the controls. I'm stuck in the situation where I have to assume you didn't read the help menu, because I can't understand any other way this game would be incomprehensible.
