This game is really cool! I really love the idea and I would definitely buy this game if a few changes were made. Firstly, the game is a too easy at the moment. Many times I could just sit back and do nothing and got 100,000 points which was cool to watch but didn't provide much of a challenge. I think you could probably borrow the scaling from something like Balatro. I think you definitely need a way of selling your bumpers/balls, just to make sure the player has choices to make between rounds. Another option would be making bumpers limited use, so you could have them disappear after they have been used a certain amount of times. Really cool game! I hope you expand on this in the future! :)
