Interesting idea, sort of reminiscent of retro sports games like Track & Field! To add to the feeling of momentum, there could be more mechanics related to when each key should be pressed. For example, when the cane is standing straight up, you want to press left to make it fall to the left. After that, you want to press down to increase it's downward momentum. At the bottom you want to press right, and so on, in a circular motion. As far as I understand it, now it was a matter of how fast you press WASD, which was fun as well! Nice job!
