I have liked tower defense games but I don't like the idea that you can instantly make more towers while being attacked. I also disagree with the enemies getting so much stronger that you have to upgrade towers. But then if you can't build towers of upgrade towers in battle what fun is it to watch you base get attacked. Well I have thought of two different ways to do this and perhaps use those ways together.
-Combat is shortIf the entire combat is short and intense then the players interest will not be lost.-Give player Combat abilitiesLet the player direct fire, call for air strikes, or temporary shields on a selected towerThis game is working but not ready for showing altho it is much more fun right now than that crap last game that I rushed out. I may release the WIP if people want to see it.
