Pretty fun. Although, as the game goes on, it gets too easy and boring. The hit detection is a little odd, and try to add an animation to the character. Overall, I like this game. 3/5. :3
The curved weapon requires you to get a combo of 70 or higher. You can increase your combo with your tension bar, which you can do by scraping, which is going close to a bullet, but not hitting it, or getting close range kills.
