Boring yet fun and well animated/drawn.
The art is great and well shaded. The animation is smoth and clean. Their was a good selection of music and great sound FX.
It does get boring quickly though at the same time it grows on you. You do kind of want to blow up as many as you can and get a high score after playin' a while.
I'd like to see upgrades and more types of enemies. I'm sure you'll do great next time. :]
