OK, another proof for how predictable human beings are - it's all about mean value and standard derivation on a certain level of confidence - my statistics teacher would go crazy about this one ...
cool game BUT too gast and too hard. a good td should give you the chance to buold a proper defense line before the tough guys come. it's all about having fun, which goes down the tube if you die after a couple of waves.
I liked this one pretty much, but there are some drawbacks:
1. Why can't I play the missions in a row? After finishing the first one going on with the next would be comfortable.
2. Not enough units, not enough tactical depth. Units should have more strength/weaknesses, e.g. spear man are more effective against cavalry and so on.
3. Enemies do not attack my territory. There should be more dynamic in the game play.
Beside these points: well done. 4/5
