the game is slightly difficult before you notice how OP the wizards are. after that, it's just tedious. you can immediately upgrade all your towers to ice and give them double cannons at the start of the level, farm for gold, and send out your highly upgraded wizards until you win. after wizards you max out knights so that after 10 minutes of watching your wizards destroy everything you can make a futile attempt to speed up the process. it's not the worst game i've ever played, but frankly i'm surprised that this game is scoring as high as it is
