Too bad it ended like that, with the 8-2 act update i tought it will bring new scenes for the already know Zombies... because in the 8-2 you have at least 1 new type of Scene with the "Z-Dog" so, why not add it to the rest of the game?
I understand if we talk about the worm Z (it's obious it will be just Game Over if it reach a Girl) but...
Honestly i think they could edit that part..
Make the Worm-Z, be able to F.. a girl (making it count 10 of 100 of life) making it more difficult to save the Girl and of course! if the Worm-Z reach -100% it could be a GAME OVER scene... (we know why)
But with the others... at least, just unlock the gallery (wich can have the Game Over Scene) while in the other part, it just be... a F.. scene without ending the game..
That's what i think..
It's a good game, difficult on some parts of course unless you move quickly and else.. a little with bugs.. but good.
