Very short, interactive flash animation of a magical girl with a giant hammer fighting an evil nail. It takes maybe five minutes to complete. To start, you must press H or T as prompted when the girl swings her hammer. Do that for a few times and you unlock the endless loop mode where you can press either button (H/T) to keep the animation cycling. There is also a mini-game built into the title screen where you must press the H or T buttons as they light up. Do that enough times and you unlock a gallery of individual frames from the animation, as well as some sketches for character ideas from the same world. The animation and voice acting is decent, but the UI is poorly designed and the endless looping fight is unsatisfying.
