Currently there is a very popular app called btd4 on ipad/iphone. It is a tower defense game.
I wish someone can create a similar app with the following:
a) upgradeable towers
b) easily customized maps
c) easily customized enemies speed and hp
d) the whole documentations
Basically the graphics ARE NOT important. I just want the logics behinds.
And wish you could make a very intuitive documentations on how to customize the game.
The budget would be $100-$200
