Hmm...
It was alright, but I don't think the level design was very good. Maybe letting fellow NGers make them was a bad idea?
I think the game could be a lot more fun if the cow would move around more. As it is I don't feel like I can smash all of the plates and it's just a few smashes before watching it fall a long ways. In these types of games you want to see the projectile keep going as long as it possibly can and continue to destroy things.
Anyway, don't listen to those jerks who gave you 0's this isn't worth a zero, but I think a few little improvements would make it a lot more fun.
