Forgot to add this in my comment but also there is quite a sizeable amount of lag, unfortunately, when trying to field lots of troops, although this is probably true for all games
A really great game! However a few suggestions for this that might be nice would be, a speed up button or just increase the movement speed of all troops overall, a "help" button or "?" button in the corner of each of the tabs (like tavern, barrack etc) that would bring up the instructions again instead of having to make a new file, adjustable volume levels of music/ effects (imo the sound effects are abit too loud but that's probably just me), also in blacksmithing, the chances of producing good equipment using only materials of high "power" are a quite low, perhaps if you only used materials of say, power 5, to make something you would be guaranteed at least a stage 3 (or something like that) item. Lastly, perhaps there could be a small amount of bonus gold for completing a stage for the first time.
Overall though, a very enjoyable army game, I'd give it 4.5/5 ! :)
Maybe there should be a way to earn coins apart from just buy them like perhpas there sould be a levelling system or something where you'd get coins for levelling .
Wth on my darkness account it says after 5 days I get 2 cash for daily reward, but on my Kong account after 5 days I only get 1 cash! NOT FAIR ! plz + so the devs can see this
Perhaps there should be a sort of "cap" on how many zombies there can be on the screen at the same time, especially in purge, as I lag a lot as the zombies keep endlessly spawning. Maybe something like 10,000 ? Great game otherwise :D
