Regarding the Balance, we had a mistake on the update, that will give too fast too much business speed. Even at the first levels it was not too bad, at the higher levels it was too much unbalanced.
We are working in a proper balance for the game. Apologize for the inconveniences
The % of Accuracy it mean to be the times that you hit a zombie and not fail. So if you do not fail any shot then you will have 100% accuracy no matter how many zombies you kill.
Hope it makes sense.
Thanks for loving the game.
Having to aim ahead was the idea of time since you shoot and then the bullet arrive. And it's a really important part of the game.
Well this is my first shooting game, still a lot to learn.
thank you guys.
Well this was a first try, so, nice you are so critical so it can be improved.
@Envidor: Autofire will ruin the fun of the game.
you can buy new weapons as soon as you go to the next level as it will be unblocked, and it is explained once you passed the first level.
This is a really difficult game and you have to master the secondary weapons to beat it.
Thanks for all your comments though
