Yeah, needs improvement
The thing about this that I liked the least was how there was no sound or music. I always look forward to hearing the little plink sounds the ball makes. Another thing was that this had no play button. Thirdly, I think I was unable to continue the game after I lost a single ball as nothing happened when I lost my first ball. Maybe there could also be a background. I will say that the only thing I liked is how it was easy, if too easy.
In fact, I had most of the blocks eliminated before the ball even touched my thing for the first time. Please try to work harder on a game next time. I always encourage people to get good grades on projects. You might also want to have more things going on like stuff coming from the blocks that are destroyed. Powerups are always cool.
