Your music track was well done and matched the frenetic pace of the gameplay well. I was a little confused by the powerup. Sometimes I'd get it and stay larger for a while, other times it seemed like it was gone after just a few frames.
This was a fun little brick breaker, but I did encounter one bug. I must have hit just the right angle. My ball just kept bouncing left and right and left and right:
Maybe code in some sort of detection that kicks it out of that zone after a certain amount of time, or at least provide a button option to reset the level. I just refreshed my screen entirely and started again. Mr. Boss had to save his employees after all!
Good work.
