Those are awesome things to consider! You're right, it was partially generated, or i can say rephrased. I was worried about the use of the word ambitious too.
I did not even think of the addition of towers. I was brainstorming more along the lines of adventure-like exploration; not to say that towers would not be a great addition to that!
I don't have experience with game design, development, and the other talents necessary to complete an indie game (especially one of this scope). I've followed many indie devs at youtube and i think you're right. And while this isn't my dream game, and it may take a lot of discipline and hours, I feel confident I can complete a game like this. I guess it's a good sign that you thought of this as my dream game :D Made me chuckle!
