Thanks for playing my game! I really don't know what kind of music would fit this, so I just picked the best I could. And yes, it is supposed to be some sort of idle game, you see the numbers go up and feel satisfied (I know I'm very satisfied when I saw the balls going around and breaking blocks :))). Maybe if I were to expand this, I'd add achievements and unlockables, and more upgrades, and I can even make a lose state as well (the blocks will constantly go down and you have to break it fast enough, but for this project specifically I kinda headed towards the no lose type of game)! I think that would make it much more fun. And thanks for the feedback about purchasing upgrades. That could definitely need some attention.
