destroy towers by right clicking
Heh, I totally missed that. Why the right-click is used for both moving and attacking? That is extremely awkward, at least for me.
make attack automatic instad of right click?
Why not put in on the left click?
you are suggesting that towers attacking from fog of war are revealed on minimap?
At least those which are in the walls and thus remain invisible no matter what player does. Alternatively, you can modify map generation to put towers only in the corridors.
Now that I understand how to get upgrades, they seem to work – not much to say since currently they are very basic, which is normal for first prototype.
Good luck with development.
