use with credit the speed of the green slider depends on how long you hold or let go. for example, if you hold till you're about to hit the right edge, it will be harder to bring it back left since the speed is higher. clicking several times you will see it stays almost in place because the speed is constantly being minimally changed between a bit of and below zero, but it is harder to recover from a greater speed number when trying to go the opposite way if that makes sense. if you hit the edge however, it resets to speed 0 for better recovery. the bar at the bottom is merely a placeholder for progression towards fishing successfully. (if it were to completely go right then the fishing simulation would stop and you would succeed, but I would likely add a timer for failure in a real implementation of this engine.)
