you better make a sequel
man, for a first flash game, this is more than amazing mixing zombie killing, with very good gameplay and great graphics this game deserves the best rating if i may make a suggestion, instead of 20 days move it up to 100, with better story elements like every 10 days something should happen like you hear something on your radio saying there is help on the way but you got to survive for 100 days, we should be able to save our game, how about during daylight you can go into town yourself and when you go into a buidling you have to fight the zombies that were taking refuge from the light. you can find survivors hiding in closets and stuff like that PLEASE MAKE SEQUEL I LOVED IT!!! oh, yeah be able to customize your weapons like faster reload or stronger and make explosives like grenades or a rocket launcher
