Strength training gets impossible to complete at mission 17 for people like me who have muscle problems in their hands. Might want to do something about that.
First Tower Defense game I've played that REQUIRES grinding in order to proceed. Most just rely on smart tower placement, but not this one.
You HAVE to grind, or you'll NEVER proceed past a certain point. Where's the strategy in that?
Oh I'm sorry to hear that. I'm not sure how to balance things, but in the future I'll provide more control scheme.
