Got this to replace vectorTD after ios5 rendered it unplayable. Works great, i dislike all the cartoony td games. Dunno why people complain about no directions because its intuitive gameplay if youve ever played a TD game. Great overall game. Would definitely buy again. Would be even better if there Was an option to sell/upgrade towers. Also the ability to Build while in pause. (maybe I just havnt figured that part out yet) thanks for the great app:)
