I liked this game because it was a perfect difficulty. This game has a simple design, but it's still fun to play. The graphics and audio are also pretty good. Good job!

Score: 185. Was a fun time. 

Good choice to use different size blocks otherwise I could have just stayed at the bottom of the screen and let my bullets do all the work.

I would have liked to see the theme pushed further (e.g. collect red blocks).
