I'd give it a pass
In response to a few reviews below please note the following.
This game is not a part of the Lunar RPG series. This has nothing to do with silver star story or eternal blue. This game is based off of the Boktai series that were on the GBA.
This game is more of a shooter/puzzle solver than a classic sense RPG. Combat can be compared to that of Kingdom Hearts or Sword of Mana. Honestly I found this game somewhat difficult with random difficulty spikes and tough bosses that seemed out of place. The game just can seem frustrating at times all of a sudden. It is also a bit short.
I wouldn't recommend this game unless your a fan of the series. If you still wanna give it a try the price point is completely justifiable though.
A Disappointment Review
To me this game was going to be a good add to my Lunar series collection but when I started playing it, I was really let down. The gameplay was alright not great, the graphics were below average even for a old style RPG. The sound was alright but yet again did not overwhelm me. The overall appeal of the game after two hours of gameplay was of pure let down when considering the fantastic experience of some of the other games. My advice, go back and play the classic Lunar games of old.
My Favorite DS Game
This game is awesome! Even though it has an E 10+, it should not be overlooked. What are you doing? At $9.99 you should go and get it!
This game has the element that all RPG games should use . No turn based fighting all full force actions. where you do everything yourself. The game is very addicting the musics ok but the game overall is Good. May not be for everyone but I sure enjoyed shooting and slashing things up.
