Card Crawl is a diamond in the rough. By rough... I mean the Apple App store and by diamond... I mean a good game.
Card Crawl is kind of like playing through a tactical solo dungeon crawl... with cards. It's also a little bit like solitaire? I feel like I'm not doing a good job here. Stick with me, the game is good.
What happens is you are dealt a hand of four cards and you have to manage them. They're in the middle area which represents the dungeon. There are six types of cards in the dungeon and a few ways to deal with them. The card types are shield, sword, coin, potion, special ability, and monster. All of the card types can be dragged down into the section around your character, but the catch is that you only have two hands and one backpack. This means only three items can fit on your character at any time. Monsters, on the other hand, can be attacked with swords, get hit by special abilities, be defended against with shields, or dragged directly onto the character to deal damage.
As soon as you clear three of the four cards out of the dungeon area you will be dealt three new cards to fill up the empty spaces. The goal is to work your way through the entire dungeon deck without having your character reach 0 health.
It's super fun. It plays really quickly. And it's a little bit addicting... in a good way.
I highly recommend it. Especially since it's only $2 in the App Store and doesn't have any of the F2P/In App Purchase bullshit attached.
