That's ok...
This game is just ok.
I like defense game. But this one is border-line. Zombies defense games should be a little bettre than that...
There's few (lots) points you should work on:
- Okay. The kinda really ANNOYING MENU MUSIC (Gun menu)
- Should have a better concept. It's too simple. Uprade and fight... if you could put more guns it would be okay.
- Better animation OR Good-Looking zombies. They look like my little brother's attempt to draw my mom.
For the rest... I think its okay
