This is a collectible card game (CCG) with a few riddles thrown in for good measure.
Storywise, there's an attempted assassination and a conspiracy to uncover. You do this by traveling around the world map, exploring locations and fighting baddies.
The card game is fairly simple. You can have up to 3 units, limited by your command points (gained by leveling), and each unit can take one action per turn. An action is playing a card, whether an attack or a boost card. Units have built in cards that you get by clicking their picture, these will refresh after a while. You attempt to get high attack values, so your attack cards will penetrate your opponents' defense values, damage and eventually kill them by reducing their health to 0. There’s both physical attack and a number of different magic attacks, and it’s really impossible to guard effectively against all of them.
Since cards do not have casting costs, only costs to obtain, there is rarely any reason to use lower damage cards, unless they bring some sort of debuff or damage over time effect. You can only have 12 cards in your deck at a time, from about 100 that you can obtain, and since most of them will be lower tier, there is very limited deck construction. Balance is definitely an issue, what with no casting cost, and some of the units are really overpowered. Generally speaking, the 5000 cost cards are the ones worth the price.
The AI is not anything special, most opponents can be easily overwhelmed if you build a half decent attack heavy deck, with a few buffs and healing thrown in. The sole exception to this is the broken card which switches your hand with your opponent’s. When the AI uses this on your tuned deck, and you get a hand full of crap, there’s a good chance you’ll auto lose.
There are a number of bugs, ranging from a quest that may become uncompletable to text that doesn’t properly reflect the gender of your character, should you choose the female avatar. For most people I imagine the 4 chapters of the game can be completed in 3-4 hours, less if you’re an experienced CCG player. As you near the end of the game, the English writing gets progressively worse, giving the game an unpolished and unfinished feel. This is further compounded by the ending which doesn’t resolve much.
Graphics and music are decent enough, though there are some issues with the cropping of the character images.
I would cautiously recommend this game for people in need of a quick CCG or simple RPG fix, but you have to take into account the simplicity of the card game and the short length of the overall game. It starts out fairly fun and refreshing, but once you understand how to best stock your deck and obtain the power cards, the excitement tapers off.
