Glitched when I left the game for a while and came back to it, so now Rena always points right even when not shooting?
If more information helps, I left when I got stuck on the twin boss that just tries to run me down - after the glitch, used the cheat, and still had trouble because I had to hit the second one before it killed me.
...And when I gave up and killed the two-stage refight boss with the cheat code, I found myself unable to continue; there's a door in the floor that I can't seem to do anything about. So I'm reloading.
