Very Excellent game, although, I have some suggestions.
1. Make a sequel-If this game is awesome, Imagine the sequel!
2. Put online multi-player in the sequel- I dunno, something like bunker defense.
3. MOAR GUNZ!-Cats cant get along nicely without guns, or chzburgers. (something like a sniper or a mounted gun)
4. Ranks- If you make a multi-player, you should add ranks-Pyromaniac, commando, private etc.
5. Maps-this should add more fun to any zombie game!
And, i guess that's all press the plus button if you want these suggestions and a sequel.
