Though the game is a bit childish; it's still a very fun game.
There are a couple of flaws in the game though. There's a lot of bugs in the game. Nothing too major to not allow you to play or anything like that, but small things like walking through walls. The game can get tough at certain times and require lots of strategy so you don't lose an ample amount of minions. Forging good weapons costs A LOT of resources. They could have added a lot more items to customize your tower. The graphics are not good and the save system is absolutely TERRIBLE. Camera can be annoying and so can the targeting system. Your character, (the overlord himself), is rather weak and can die rather quickly. Even with the strongest of weaponry you're almost no match for a single crossbowman. Not enough spells.
