Marble Zombie Massacre what?
this is bullshit
1. the lvl design is as simple as possible
2. when i need to shoot like 30 zombies the zombies look just like a brown line slowly coming towards me
3. the background is somewhat good for a zombie game. maby change the background each round?
4. a green bubble? whats up with that?
5 the gun sound gets annoying
6. and so on!
please make it better.
