Fun casual collectable card battle game. I played for around 1.5 hours and just beat Cthulhu. You can play more if you like and collect more cards and defeat harder modes. I'm guessing it would take around 5 hours to obtain all the achievements.

+ Fast paced, hard to put down, addictive
+ The art style and monsters are really colorful and well drawn, original designs
+ Lots of cards to collect, intricate fast paced battle system, you have to think and act quick
+ Lots of value for only $1, hours of gameplay
+ Good sense of progression, never stuck, always unlocking new stuff

- The monsters are not H.P Lovecraft designs, the last boss is a funny looking Cthulhu but the rest of the monsters are just original monsters. Would have been better to include Dagon, Nyarlathotep etc...
- If you don't get the right cards, its nearly impossible to win
- Sometimes the battles can be a bit too fast paced, causing you to accidentally play the wrong card

Overall Rating: 7.5 / 10 !

Straight-forward, balanced and engaging
