A fun game, although it has it's setbacks....
The game has 13 or 17 areas or so, and they all contain enemies that have different glyphs to absorb. Each glyph is in its own class like piercing, slashing, blunt, fire, dark, that kind of stuff that are super effective and less effective against certain enemies. Each kill you make, you're profiecency in that glyph class goes up a point or so ( different depending on the enemy ) and overrtime you get more powerful in that class. This is only worthwhile if you get several thousand points in one class, as when you get a point, your profeciencies can go up by hundreds and it won't effect your damage rate ( it goes up that small ).
If this makes any sense, the game is short and long at once. You fly through all the locations pretty fast, but they are small with not much content. They do have their share of detail and hidden items and enemies, but they are still very short. Once you get to the end ( not long from the beginning ) you'll fight Albus, your rival, absorb the final soul dominus, use it, and die. The game ends here, but humanity is saved ( yay ) However, here you find out about all the villagers you didn't find. Find them and you have another 1/3 of gaming to go. You can also do the sidequests of the villagers, but hthey usually don't require more than a couple minutes ( or ridiculous amounts of time if you're required to find rare items ). I rate this game as good, and very fun, but not something you should go seriously out of your way to buy.
