Cool
Very interesting game, I like how you can upgrade your towers- I hate the games that wont let you upgrade anything (that REALLY SUCKS)...... Great game.
good BUT...
this game is pretty decent BUT the difficulty is IMPOSSIBLE!!!
alright
good game. great idea. pretty difficult the 1st couple tries. couldnt hurt to make some of the upgrades cheaper or some of the monsters worth more. and the monsters health goes up way more than handlable between rounds.
....
this game sucked and there wasnt a whole lot 2 upgrade and it was hella hard
