The concept of this game is pretty cool. It would have been great to see this game with some added visual effects and a camera shake to bump up the feel. The clean and minimal look gives quite a charming look, but you need to think of a factor to increase retention and make the player immersed in the gameplay.
Thanks for the feedback! I was hesitant about camera effects was because it would disrupt the player experience; camera shake when you're carefully balancing objects is something of a hindrance. Some extra visual effects, for sure, would go a long way: Some chroma split effects as the falling balls hit the objects would fit the overall theme nicely.
