So I collect all the crystals place them in the respective towers and when I get to the final one there's the boss waiting for me but the thing is he doesn't do anything !? Whats up with that,I just walked through him and into the tower and then I finished the game with no final battle.
I don't think this is what is supposed to happen,has anyone else experienced this?

I know this is an old thread but I just wanted to say that I encountered this same situation. Very odd. Can't say I'm terrible worried about it though, the combat is horrible in this game. Not the way it looks but the fact that you stats are meaningless and the computer hits more often than you do.
