I didn't expect to love this game as much as I do. I paid for no ads but I wish I did it about 500 levels ago haha. I love the new colors they just implemented on the blocks. Just a suggestion-maybe give a way to work towards customizations like daily challenges or something and different color balls, backgrounds,etc. BUT, there's multiple levels that I see over and over. I'm just wondering if I paid for no ads to play the same levels over and over again haha. That's why I'm giving 4 stars.

LONGEST ADS OF ANY GAME I HAVE PLAYED. CRAZY. 1 MINUTE ADS, OFTEN. About 3 levels between levels you can't beat without tools. Tools are charged 900 to 1900 points. You get only 20 points upon completing a level. 40 points if you watch long ads. Do the math. Without points, you must pay $$ for tools. The game itself if fun, but the fun is short-lived.

Out of all the carnival, knock-cans/blocks-down games that popped up that I have played, this is the worst. The physics don't match up. Most similar games, you can break glass jars 2 deep before the ball loses momentum. In this game, one jar stops a ball and may break. There are some levels with 1x3 concrete blocks that are 4 deep that take several balls just to create separation to knock down. I'm giving 2 stars because the portal cube blocks were a unique touch.
