Apparently endless content in this \"Castillo Defense\" style strategy. Perfect work and very adorable characters. Fantastic art and a real challenge reach the end of the game. It\'s free, so give it a chance! Update: Two years and I still love it! I have played every day since I got the game and developers put so much love. Try it, it\'s free so you have nothing to lose ~ One of the two tower defense games and the only porridge that I liked. Well designed and quite intuitive, with free heroes that are worth a damn and a handful of faster free heroes to begin, a decent story, although incredibly prolonged, a great art, a good translation and without ads, Arknights is the gold standard to which all mobile games should aspire. Salta the new voice packages in English, however, they stink. Great game with incredible music and a very long history/construction of the world. Many characters and most of them have a serious drip. Gacha is decent, but very good in the sense that you do not need to replace just because you did not understand that type/lady that everyone speaks. The difficulty varies from the first level in a Kirby game to \'The Dark Souls of Tower Defense\'. The enemy design/mechanics varies greatly, once you go out of the first two chapters, just like maps. Art is really well done. Level designs and base designs are also incredible, it is a simple cubes design that I enjoy. If you like the tower defense games, this game is for you. I also believe that the HUD for the menu is also well done and feels soft. However, when I make missions, the screen darkens and it is as if a character was giving a dialogue, but I can\'t see it; If I take advantage of several times (as if you continue the dialogue) I replace me in the game. IDK if it\'s a mistake but please fix Fantastic tower defense game with beautiful characters and works of art, convincing history and writing and an elegant user interface. The only queia I have is how small the text is and how there are no options to adjust it. At first he turned off to play and turn off many friends that I have to prove that otherwise I would be very interested. Consider text size settings in future updates!
