Nice concept, with addictive clicker controls.

Like the reduced art style and the use of colors - both for the game elements and the UI. Looking really good! Same for the music + soundFX.

As for the game play, I have the feeling something is missing here. If only I could tell you what it is...  The mechanic as it is now is solidly implemented, everything works like a charme.  It is clearly a game best being played on a touch device, so I won't judge it for the mouse  inputs. The true weakness is the fun part. I feel like the missing "thing" is just around the corner - some twist that needs to be added to bring the meachics as they are now together, adding the fun or thrill that I am missing right now. I am so sorry for not being able to name it, have to leave that open unfortunately. I  want to list some loose thoughts, however, as these might  help to create a spark of inspiration.

• The playground itself constantly rotates
• The circles split/replicate by themselfs - players have  to control the game in another way
• Balls hitting the edges is the goal (so the opposite to what it is now), the greater their numbers, the better

Fun, looks nice, sounds nice, and UI is nice.
