How well can you defend your kingdom?

Devil Royale, a game that just released today, and to be honest, my first 10 minutes of the game was not that great. I thought the game wasn't that interesting. BUT! As I continued to play, I found out that this game was actually a lot more enjoyable than I first thought,. Gameplay wise this game is set up like a card battle game. You must summon your monsters to try take down the opposing enemies castle. There is a mana type regen system that as you save up more points, you can summon the minions of varying mana cost. They do not show their attack numbers on the card while playing, or the health, only their summoning cost. One thing that really annoyed me while playing, was the fact that you cannot check your monster cards while in battle to find out how to best use them on the field. Instead you need to memorize them from going to the deck menu on the main menu and read all your monsters abilities there. I was NOT a fan of this and it was very frustrating in combat because I cannot remember all of their strengths and weaknesses.
