Graphics are really crisp. Sound effects are nice and proper. Very simple TD, nothing too complicated.
However, there isnt much new to the classic TD formula. Build your defenses around key points in the invader paths, upgrade them, and try to defend your castle.
Daily rewards are a nice touch, making it more rewarding for those who play the game daily.
Im not sure if there's more, but so far, I only have access to 3 unit types. Knight, Archer and Mage. There are the upgraded versions, Paladin, Ranger and Firemage which can be unlocked eventually.
I havent checked much in the shop, but it looks like there are consumable IAP items. There are also a couple maps which can be unlocked at the shop, but im not sure if it is IAP only.
Was in a bit of a hurry coz i was on a break from work when I played it.
I think for those who love TD games, give this game a shot as it looks really nice. Just dont expect too much content or variety in comparison to most traditional TD games.
