Had an orange block get stuck on the right side of the screen that kept giving me 20 points. Currently i'm up at about 55000 points. I seem to be getting health back, though i'm not sure from what or why. All in all this is a solid attempt at flash. There needs to be a preloader or something, not a big deal really, but as i was waiting for the game to load I walked away from the computer, when I came back I had died. The game gets very laggy after a while, maybe you could add a graphics quality button?
Also, I had no issues with shooting down/right.. or any other direction. Game worked fine beyond what i've written here.

While playing, one fragment of a Red block got stuck at the right edge of the screen, where it continuously gave a +10 score boost every millisecond. Seriously, it's still going as I write this, even though I got killed. Reached more than 36000 at last count. Hilarious!

Game was fun and challenging, though.

Is one of the better things about this game by far and the game play was fun but after some time it does get old. Also there was one problem that got old and it was that the size of the game or window, what ever you want to call it, was a bit to big, I lost site of my little blue box far to many times but other than that it was a good game and one more thing I couldn't tell if I had 5566 points when i died or 9966 points either way I beat your high score :)

The game is great. However the game just starts you off the bat with nothing go on. And it seems like this game can go on forever.

I would recommend a menu and a pause button.

Generally a fun flash, good work, sweet music too, I like it
