I feel like there was definitely an aesthetic charm to the fact that at its core, this is a very early video game, but there is a heavy weight on the fact that millions of block breaking variants and clones populate the internet. However, there are many opportunities to improve and make this a pretty neat little game. I will say I was curious by the title, and definitely felt relaxed and eager to finish at least a level.
I think the art was good, it definitely had an MSPaint feel to it, but I still felt as though it could be smoother and a little even in places such as the lower grid. I enjoy vaporware imagery and music, so I think it would be cool in future additions to have additional levels with more art, and perhaps soundtracks?
I feel like the physics could use a bit of tweaking, but I think you're on the right path. I feel like considering the content of the game, it could probably go with a few notches down on the speed of the ball.
