I don't get it... if you were going to go through the process of using all of RPG Maker's assets... why didn't you just... use RPG maker to make the whole game..?
I find this to be a little TOO easy. I was able to finish every difficulty, from easy to hard using only norton towers... up to their third upgrade, max.
The game is definitly good, the only complaint I have is the music. This is by far the oddest, and worst us of the RPG Maker XP music I've ever heard... it... just really didn't fit the game in my opinion.
