King Of Defense: Merge TD APK 2.0.12

5 stars: You can spend money, but you don't need to. You can get a good amount of gameplay for free before you hit a wall (I've at least unlocked the 2nd world so far, still going). It doesnt force you to watch ads, but the rewards for watching the (lots of) optional ones are decent
5 stars: It's not intrusive, it's creative, fun, challenging, and very friendly UI. Very recommended!
4 stars: The gameplay mechanics are great. Combining tower types is a great ability that sets this game apart from other tower defense apps. I haven't felt any need to purchase anything so far in order to win, so that's a win. The downside is the grammar; sometimes the English translation is so bungled that you can't understand the directions. Doesn't make much of a difference on gameplay though, just makes the game feel cheaper.
