I don't mind about the young voice saying "Rampage", I already thought that it is probably a family member. However the achievements are not working for me, I tried reloading the page, still they won't work. Simple and nice game, also the artstyle may be a bit strange when starting the game, but once you get settled you are used to it. 3.5 because the game needs some fine adjustments like becoming a bit more complex in its mechanics, especially when you have a real horde. Perhaps a minion automatically picking up and using the brains would be good or having some more skills you can use, also I would love it if you had the option to upgrade the rampage :D Pretty standard game so far, but like I said some more adjustments to it and it would be really good in my opinion.
