This update's main features are difficulty settings and a flexible squad composition. Now you can choose who to send into the fray!
- Added a step before starting new game to customize your squad a bit; this means you can now choose your avatar, color, hero class and change the hero name.
- Added a difficulty setting; you now have three choices: easy, normal, hard (rough). Easy will have 1 color less on the board, whereas hard will give you additional zombies to deal with.
- Tweaked BGM logic a bit, sometimes it wouldn't select the next audio clip
- Added Chinese (simplified) translations
