it gets boring fast, the ball moves really slow and the game takes a long time without getting harder

This game has been modified by so many people, but whats different about their modifications is that they added more to it, like upgrades and stuff. yours lacks in in upgrades, and even music, and i hate a game without good music, or any for that matter. it was boring. i suggest you try again. message me if im wrong, but im pretty sure not many people like, or will like this game.

try to fix this the ball goes left to right on the fourth bonce

After fourth bounce, ball just went back and forth from left to right. Game is too slow.

Not too bad. There are some things that need sorting out though. The spinning guy at the bottom is very distracting. Also, make sure the blocks are evenly spaced out and it would make it look much more professional. Make the movement speed of the ball much faster, maybe twice as fast as the gameplay is very slow. It is boring waiting for the ball to come back down again. I don't really like the play button at the main menu, but that could just be me. And you need a retry button on the highscores screen.

On the other hand, you have a very nice intro, and a nice menu background. It is a good concept and it could work quite well but it needs some work to get it up to scratch. :)
