I'm going to be blunt... this game is badly overrated on vndb. I was - quite frankly - amazed at how poorly the story was told... it was like looking at a bunch of disorganized pictures set on a wall and trying to make an actual story out of them. The protagonist is your classic cipher for the reader, and the female characters basically exist to have random sex with the protagonist. The actual battle system is nowhere near as refined as it was even in Force, despite the fact that Revellion is a remake version that should have logically seen an upgrade there in addition to the major visual upgrade it got.
While I see hints of brilliance here and there, this game fails miserably at getting you to care about what is going on, mostly due to a lack of emotional investment in the characters in general. Quite frankly, I'm regretting my purchase of this game. They upgraded the character designs to Baldr Skydive levels... but they failed to revamp the story, which really needed it. It is also unbelievably short, which is probably why it failed so badly to get you to care about what was going on.
