I'm actually using Unity's newer input system which is all event and action based but could you give more details on what controls don't feel as tight as they could be?
Really glad you enjoyed it though and are appreciative of the smaller touches I added in like the fire. I'm hoping to add more elements like that as small background details that add to the fun. There was actually a lot of thought in the ball movement as well. I was trying to have things make sense but allow for a lot of control over the ball to allow for defensive tactics and set ups.
