Depending on if you look down or up in minigolf , the power changes, even if the power meter is full
This issue comes out more mostly from areas like the Kingdom map with their ramps which many can’t get over unless they know of this issue, the video below shows the same thing in a controlled environment.
Looking “down” increases power while looking “up” decreases, an extreme case of how much it harms in the video by looking more up then top-down.
