I would like to see if you can beat city TD

Its always better to ugrade tower istead of making another also dont make aura towers until you get really good towers or max towers, im gonna explain: if you build evil tower for 5k g with 30k dmg. Its better to upgrade it for 7.5k g instead of buying another one, 2x 5k g towers deal 60k dmg per sec but if you upgrade then you get tower that do 75 k dmg only for 7.5k gold. So you get 15k dmg extra plus its cheaper 2.5k gold. And about auras: until you get value that equals cost of new tower its not worth you would need 5 evil towers to get value from 30% dmg aura but theres the point that its not worth to get 5 low lvl towers to get good value of the auras. So simply Always upgrade your towers instead of stacking them and always get auras when you reach max lvl towers. (you can affort to buy 10% aura in middle game but dont upgrade). This is just mathematical facts about this map dont consider this as hate its more like advice play it as you wish in the end its your gameplay : D

you know what this is
