Hello,
Without any doubt, the concept of this game is pretty unique and the music selected for the simulation is also quite good. Though there's a lot of screen resolution problem which ruins up the feel of the game which can be solved in the Unity Editor itself, try checking it in the project settings and change the Screen Resolution/Aspect Ratio. Also, one odd thing which is quite confusing in the game is the target or the destiny we want our ball to go, that's quite unknown and hard to predict. So a visual element for destiny like a door could make it more sense. Lastly, sometimes it feels like joining the boxes and creating a connection doesn't make that a difference and feel useless, so introducing some good puzzle element relative to these mechanics is still needed to be polished.
