This is a pretty good Arkanoid clone with a lot of promise. I loved the particle effects and overall the game ran very smooth. Well done!

I believe this is the first Silverlight game submission; congratulations on being the first! :)

Now about the game. This was actually more fun than I was expecting to tell you the truth, but I see it's still in development, so it'll probably be even better later on. I think you should definitely add some kind of splashy congratulations when beating a level instead of just immediately switching to the next level up as soon as the last block's destroyed. I like how the pieces from the blocks gather up on the paddle.
Keep up the good work!
