Decent TD game with some unique elements to it

Not a bad game, functions as a tower defense should. Nothing about it screams awesome though, I get that it is tower defense but this is pretty basic.

i just wonder is it possible to beat this game or its endless?

fun simple and addictive but damn, level 50+ is when shit gets real XD

the game is pretty cool and gets harder along the way :)
there is only 4 soldiers but atleast you can upgrade them
there could me more than only one map though....
i suggest putting tons of vanguards on front and put specials near the barn
