average...
or just above. it was slightly origional, because the Zombies actually did something to harm you instead of just standing there or scratching you. haha.
graphics were ok - zombies looked cool.
animation was nice - those shape tweens looked cool.
sound was alright - a great sound effect from 'defend your castle' there. but i would have liked it if there was a sound effect when your gun went off. also, good music to go with the game.
overall, not too bad. obvisously it couldnt keep someone entertained for long, but not bad at all.
overall score: 6/10
