Pretty good overall! The graphics and sounds are nicely done, and the musical track certainly adds to the somewhat mystical atmosphere of the game. However, the game's plot, although having a concrete conflict and goal, just seems somewhat obscure. Perhaps fleshing out the backstory or giving more information on these dragon creatures could help to further captivate the player as they play the game.
The gameplay itself has a few minor issues, the most agitating of which is the lack of a pause button. Also, as the previous reviewer stated, it can be tedious to exit to the level select screen to find that your progress has been erased. Finally, now I am just nitpicking, but I think those are hexagrams, not pentagrams.
This game could use a few alterations, but it is still a rather decent game with nice sound effects and visuals.
