I have a disability which limits my use of my hands.
I cannot move fast enough to tap in many games.
I tried Fieldrunners and it was great.
I tried a couple of others - like Tower Madness - at full price the day before it went on special but they need me to move too fast, and they don't let me place towers while they are paused.
Can anyone help with the names of any other Tower Defense games that allow you to pause during the waves and let you place/upgrade towers while you are paused like Fieldrunners?
