Updated review... Contacted support, got an update that fixed the issue. Enjoying the game since :(

西涼太守

the game became very very boring after stage 370 something... flying monsters bypass everything, no more strategy applicable and purely a tower upgrade game. I quit at stage 384

its good but I cant ever load back in. everytime I exit the app and try to go back in.. im stuck on the main loading screen that says "remote setup" im connected to wifi and everything. only way to fix it is reinstall but then it'll just happen again.

Started out as 5 star, the game was fun.. The massive ads for everything and the pay to remove ads were extended. The more you grind thinking, "Oh, i'll get a good hero /tower," the more you realize starting a starting and zombie apocalypse and curing it , is more probable than getting divine weapons and gear .. unless you pay the ridiculous prices. great game, unfortunately not worth the time or effort .. Unless you pay up!
