I like this game but there are two issues:
1. Its pretty dang short
2. There is a weird amount of grinding if you are going for a Platinum. I booted up my old save and I only needed to level up 4 weapons or so and it took almost a complete additional playthrough to do it. What I didnt realize is that your weapon level progress doesnt reset if you die, so its best to find a big group of enemies and just keep replaying the same section to level up faster.
