I have been playing a lot. Its really fun and entertaining. I noticed that if you play in mobile. After selecting stickers, it autoselects the best route to throw the ball. Which makes it kinda an overkill.
One thing that will add a lot more synergy is that when you win a level with a lot more points than its asked of the level. It should reward you somehow. Like maybe more balls or maybe keep the rest of points to the next level.
