The game is fun, without the lack of proper management of the units and shoving them inside a defensive walled city, everyone is gonna be dead when night comes sadly.
The difficulty is not that much if you shove them really fast and expend some time making units (So you can gather resources fast and build a 1-2 walls thick stone wall), but even so, i wish the units would at least fight back.
They do the animation of shooting arrows, but they do 0 damage :(
If we could have lots of building types, and more weapons and all, i think this could become a giant survival game xD (but idk if that is the plan or just a survive waves game so lets keep at the last one :p)
