The recommendation is pretty weak because I didn't actually like the game. I think it has the potential to be enjoyable and it is fairly unique, so that alone might be worth it to you.
This game is essentially puzzle quest but with a solitaire combat system instead of matching gems. It's not fast by any means. Essentially you build poker hands to charge attacks, then launch the attacks at your opponent. Essentially you spend the entire game moving stacks of cards on top of each other to make a combo of five, and the higher the combo on the damage scale, the more the attack will do. You can also 'steal' cards from your enemies so long as they aren't stacked.
The combat is cool once or twice, but after that it becomes so repetitive. Nearly every fight is identical, save for the select few where you need to charge and use special attacks to win.
Beyond the gameplay, the music, sound effects, story and graphics are all ok. They're mediocre, they're fine, they're acceptable. Without a doubt they are not great and won't sell the game, but they sustain it without detracting.
All around, that describes the experience: alright, ok, passable. It's not thrilling or revolutionary, but it is unique and if that's what you're looking for in a game then you'll find it here.
