Perhaps one of the most unique TD games Ive ever played, not only every elements are expanded (like a wide variety of bosses and levels) the game is also very strategic as players can choose different combinations of cards for each level, also it opens a lot of ways to make player less dependent on gems by giving them as a rewards and the availability of the gem mines as well. Now, speaking of the thumb-down, I dont mind much about the waiting for energy and tickets to play, what disappoints me is that at the beginning i was really excited that with hundred of levels awaits, this could be the best adventure as i unlocked cards and dice into the storyline, however, the more i played the more i realized the game isnt that promising, a fact is that i almost complete the entire campaign but the amount of cards unlocked covered only about half of the deck, with quality cards being the fewest, especially the rare cards, several levels are excessively difficult, typically towards the end, which i doubt could not be owned without the undiscovered cards. Also theres a lot of cards i want to upgrade but since theres only a single spot for upgrade so there are days when the game freezes literally cuz you cant advance without those cards. I hope that a new update will come soon, with more accessibilities and chances for all players.
