I really like the core gameplay of it. The way you make it into a one-button game is pretty neat. And the sound feedback is fine. But I have to be honest that as long as the visual design is a little bit better, I could enjoy the game much more.

One suggestion regarding the color design is that you could search for some color plate and try to make you game asset out of those. That would already make the game feel consistent.

Very simple game with a fun twist on a classic arcade game. Not too complicated or overdone, just a fun game you can lose yourself playing for a while.  Short and sweet. Lots of replay value. Of course the visuals are pretty minimal, but that doesn't seem to be the main draw of this game, though, since it is a large portion of the rating, it should probably be mentioned. Very fun. 

I had a lot of fun, arcade/high score games just have a way of drawing people in.  The mechanics are solid and it's fun to play!  At this point I feel like the only critiques would be maybe some art updates to really make it things pop on the screen, and a few different brick layouts or levels would really add some variety and a sense of progression in the game.  It really shows how designing around limitations (like a one button limit) can still make really fun and enjoyable games and add an interesting twist to a classic game.

A fantastic demonstration of how game jams help, is it not?

Very well done and very well executed.
