Ive seen this kind of game a few times, but this one has something i really dislike when it's tied to incremental upgrades and that is instead of a universal upgrade to all the balls the dev decides to make a upgrade window to each ball maybe to inflate and prolong the game time. The game is already as slow as it can get, the paddle dont move and become invisible if you go on idle mode, meaning you lose all it's passive damage from shoots or other things it provides. And the UI clearly shows it was made for mobile, it dont even try to hide it or have a different sized UI for PC.
