I like it! The game was engaging for several minutes, I really did want to see what would happen.
The animations are all really cute, and I love the mini map. Great work on that.
I thought the fonts were a little hard on the eyes though: especially in a game where numbers matter so much, I had a hard time getting used to them.
You also worked so hard on getting a pixel perfect look to everything, but I think the transparencies you're using for the impacts, the clouds and the smoke break the look. I really suggest you try just make them opaque. Just own the solids and use your color choices to give the impression of depth instead.
