I kinda think that the game should have an easy and a hard mode. easy could be like the past two, zombies come at you from the left, you're on the right.
In a hard mode, they could put you in the middle, and have zombies coming from the right and left. This would make the game much more interesting and harder. It'd be good because the last two were fun but WAAAAYY too easy.it'd be nice if the third one isn't a game that you can beat in 5 minutes.
