best tower defense game

Best tower defense game on iPad, but make sure to buy the upgrade if you want to beat the maps with high scores. I like the way it's straight forward tower defense, no "bouncing enemies around" puzzles, just choose the right combo and location of towers to beat an increasingly difficult enemy march. And there is a ton of variety in the maps, from free form to totally structured. And you can play 90 rounds or 300 rounds in random mode. Just don't forget to buy the free admin upgrade, and use the admin as soon as it appears in level 30. Load fully upgraded towers. Many hours of challenging fun, and 5 difficulty levels that each play a bit differently and help with learning curve.

Ultimate time killer!

I cannot add much to all these other reviews. They are accurate in the main, this is a good game. I'll add one item in rebuttal to these one star jacka$$es who can't be bothered to read the manual. You cannot place a tower on the path that the creeps have chosen for the current wave. That path is shown by the red squares when you hover a new tower over the board. To block the current path, you have to wait for the interval between waves. If you have any reservations, try the free version before buying. And read the manual if you can't figure out the why or the what.


Attention Developer

Great game. Kudos. I scooped it up during the free give away and here is my review for payment. At this time however, I'm sorry but I can't give you the full five. But here are my humble suggestions:

1) SOUNDS. we all love the sound of gun fire, c'mon

2) confusing interface. Isn't normal the same as medium? How do I unlock things? What the heck does Source mean? And what's the difference between common and random?

3) a little tighter control of admin would be appreciated.

That's pretty much it. Obviously more polish is always appreciated, but not always neccessary for a 5 star. Enough levels, towers, enemies for sure. It would be nice to see the bullets or microwaves from each tower actually land on the enemy. Overall wonderful job. A little xtra effort and I assure you you'll reap the benefits. Thanks again for the free game.
