Fun for a while... good quality sprites, though there should be more than one attack animation. Also, less repetitive music, more challenging enemies, more weapons and perhaps some trick moves or special powers would make this game a much more fun time-waster. That parts of the building deteriorate was a nice touch though, would be even better if you included fully destroyable walls... maybe you could even make a game mode where you try to crush the whole house to bits in the least time possible... who knows?
Anyway, good little game, but lots of room for improvement.
