BAH! Awesome
Awesome game.... i cannot stress this enough, best flash game on the portal.
Graphics: There is always better graphics but far sufficient for a TD game.
Sound: Well made sounds that fit the game, get a bit repetitive but its a TD.... of course they are.
Gameplay: Ridiculously addictive, kept me busy for 2 days.
Difficulty: Harsh! Missions add a nice learning curve, Up to Mission 5 its very possible and quite fun, Mission 6 is impossible to do without cheating... and even then i doubt you could pass it.
By cheating, I mean making a maze of vulcans with 2 exits, block one, let the mobs move to the end and then unblock that one and block the other, bouncing the mobs back and forth thru the maze.
I repeat, best flash game on the portal, make another pls :D
