It gets quite redundant at times. I assume the levels are supposed to get harder? the hardest level is the poker player thing, as you have to realize a hired assassin waits in the other room. Other than that, it's very easy, and get easier as you go along.
.....Markie, are you sane? DTD was not the original Tower Defense Game. There were HUNDREDS before. Besides, the battleground layout is from that air balloon flak cannon game. I forget what it's called.
I'm probably the first of the commentors to say that this game is over all hard for me. i keep getting blocked by the blocks that pop up in the first level and get trapped.
2/5 It would have been 1/5 if it weren't so addicting. This game has such a quick learning curve. If you don't get the hang of it, you'll never beat 6 or 8. You can do a lot of good with this; you just didn't.
