Thanks for the feedback! I think you were hitting the obstacles, you can jump over those with B or left arrow.
Also you don’t have to constantly crank, every rotation you complete with the crank increases/ decreases your speed depending on the direction. If you hit an obstacle your speed is decreased, so I think that’s why you had to ‘constantly crank’. I think we can explain these better and make the tutorial mandatory on the first run, which could alleviate some of these issues.
Also, we’re planning to make switching between lanes easier in the next update and allow you to adjust the length of your arm, so that hitting obstacles wouldn’t be as common anymore.
