Yeah, no, level 11 is literally impossible. The enemies can get to the cabin without disturbing the stack of towers in front of it, so there's no way to win.
It looks like the way attacks work is that every X period of time there's a roll between the two combatants to see who attacks, and the odds are based on their relative Attack values. I'm not sure what Attack speed does, since it seems like there isn't a way for the two fighters to actually attack at different speeds.
The speed of the animations do change in real time based upon the attacker's attack speed. It has no affect on fights except to speed them up or slow them down (which affects how much exp/gold you can earn over time as well as the Top-8 Duels times.)
It's not a good sign when the News tab only contains a partial TOS document, the Live Chat button announces that the Live chat has been discontinued, and this 5 year old game has a single server marked "New!"
Ok, there's a few issues. First, players can't place structures they build on the pre-existing buildings. That lead to three or four deaths as I tried to block doorways with a door I crafted myself or place ladders so I could climb onto the roof and get away from the zombies. Second, there's nothing preventing players from walking off the edge of the map and nothing they can do about it once they have. If you fall off you're forced to reload the webpage entirely
It's neat to be sitting in a giant pile of gold, but the gold-making machine isn't actually worth it. you have to spend about 700-900 gold and some population & happiness, and at the end of it you have a ~50% chance to get 20 gold at the end of each day. there's a second event that gives 60, but it's much more rare.
Neat! When the main menu says "Hard mode On", the enemies aim where you're going instead of where you are. However, that actually seems to make it easier

We will remove the Beta tag eventually, but the game will continue to receive updates and possibly bugs.
