Enemies start out stupid but after a while the squares will chase you, the circles move faster, and the triangles will shoot at you, while the big morph shape will do all three. You have to play the game for a while to get to that point.
You know, I could not come up with a viable strategy for beating the 100 challenge on DTD either, its mathematically impossible without juggling, is that also "an extreme lack of programming skill"?
To anyone who plays this. There are more than just 4 towers, there are upgrades and soldiers, you have t click on the three different castles to access the menus.
I'd like to request that people actually play 2 or 3 levels before rating. The first levels is not indicative of the entire game. :) And please READ THE INSTRUCTIONS!
Has anyone beaten it even with Juggling? I can't seem to get post 70-ish in level without Juggling and I suck at Juggling. Why would they make a challenge thats impossible to win?
