This is not a TD game. You are actively aiming where you want to shoot. For me that is a good point. The devs designed it so you unlock features little by little. At level 50 you unlock all the features... After that, it's just grinding to earn resources and upgrade your defense systems. However, there is where strategy starts. You have a good amount of different crossbows, traps and spells, but limited amount of spaces to place them; so, you cannot grow infinitely strong. Choose carefully

Lets you opt out of ads. For free. Lets you decline analytics. And it will keep you busy for a long time if defence games where you do the defence is your thing. Not an idle game. Not pay to play. Just grind to get good or try hard to plow through. Im sure there is an option to buy something, but i haven't felt the urge in the slightest after 50 levels. Save up for multiple turrets and check the leaderboard to see if you want to emulate their setup.
