Well
I liked the graphics very much. Not very detailed, but surely realistic. With the only exeption the hammer and the ''Wack'' text. No sounds? That's bad, since i'd love it if there was any, and my score wouldv'e gotten much higher. You also missed a replay or Try Again button, beacuse if you wanted to play it once more, you'd have to exit the screen and reload.
It's a good concept, but it needs polishing.
