Z! Don't Stay Still

GAME: https://play.google.com/store/apps/details?id=com.GOMW.ZDontStayStill
This mobile game is a twin stick top down shooter.
If you press the back button, you can set the number of zombie that can spawn in the level. But do not set it too high because I have a problem with the “character movement” component and still didn’t figure it out how to resolve it.
I’m making a new map and a menu with advanced option settings to lower the graphics.

Work in progress
